All Data Modeling Time-aware Predictions MLOps Generative AI


Accuracy Over Space

A model Leaderboard tab (Evaluate > Accuracy Over Space) and Location AI insight that provides a spatial residual mapping within an individual model.

Accuracy Over Time

A model Leaderboard tab (Evaluate > Accuracy Over Time) that visualizes how predictions change over time.

ACE scores

Also known as Alternating Conditional Expectations. A univariate measure of correlation between the feature and the target. ACE scores detect non-linear relationships, but as they are univariate, they do not detect interaction effects.


Actual values for an ML model that let you track its prediction outcomes. To generate accuracy statistics for a deployed model, you compare the model's predictions to real-world actual values for the problem. Both the prediction dataset and the actuals dataset must contain association IDs, which let you match up corresponding rows in the datasets to gauge the model's accuracy.

Advanced Tuning

The ability to manually set model parameters after the model build, supporting experimentation with parameter settings to improve model performance.

Aggregate image feature

Used with Visual AI, A set of image features where each individual element of that set is a constituent image feature. For example, the set of image features extracted from an image might include a set of features indicating:

  1. The colors of the individual pixels in the image.
  2. Where edges are present in the image.
  3. Where faces are present in the image.

From the aggregate it may be possible to determine the impact of that feature on the output of a data analytics model and compare that impact to the impacts of the model's other features.

AI Catalog

A browsable and searchable collection of registered objects that contains definitions and relationships between various objects types. Items stored in the catalog include: data connections, data sources, data metadata.


The second phase of Exploratory Data Analysis (i.e., EDA2), that determines feature importances based on cross-correlation with the target feature. That data determines the “informative features” used for modeling during Autopilot.

Alternating Conditional Expectations

See ACE scores.

Anomaly detection

A form of unsupervised learning used to detect anomalies in data. Anomaly detection, also referred to as outlier or novelty detection, can be useful with data having a low percentage of irregularities or large amounts of unlabeled data. See also unsupervised learning.


See No-Code AI Apps.

ARIMA (AutoRegressive Integrated Moving Average)

A class of time series model that projects the future values of a series based entirely on the patterns of that series.


One of the components of a Use Case that can be added, managed, and shared within Workbench. Components include data, vector databases, experiments, playgrounds, apps, and notebooks.

Association ID

An identifier that functions as a foreign key for your prediction dataset so you can later match up actual values (or "actuals") with the predicted values from the deployed model. An association ID is required for monitoring the accuracy of a deployed model.

AUC (Area Under the Curve)

A common error metric for binary classification that considers all possible thresholds and summarizes performance in a single value on the ROC Curve. It works by optimizing the ability of a model to separate the 1s from the 0s. The larger the area under the curve, the more accurate the model.

Augmented Intelligence

DataRobot's enhanced approach to artificial intelligence, which expands current model building and deployment assistance practices. The DataRobot platform fully automates and governs the AI lifecycle from data ingest to model training and predictions to model-agnostic monitoring and governance. Guardrails ensure adherence to data science best practices when creating machine learning models and AI applications. Transparency across user personas and access to data wherever it resides avoids lock-in practices.

Automated Retraining

Retraining strategies for MLOps that refresh production models based on a schedule or in response to an event (for example, a drop in accuracy or data drift). Automated Retraining also uses DataRobot’s AutoML create and recommend new challenger models. When combined, these strategies maximize accuracy and enable timely predictions.

AutoML (Automated Machine Learning)

A software system that automates many of the tasks involved in preparing a dataset for modeling and performing a model selection process to determine the performance of each with the goal of identifying the best performing model for a specific use case. Used for predictive modeling; see also time series for forecasting.

Autopilot (full Autopilot)

The DataRobot "survival of the fittest" modeling mode that automatically selects the best predictive models for the specified target feature and runs them at ever-increasing sample sizes. In other words, it runs more models in the early stages on a small sample size and advances only the top models to the next stage. In full Autopilot, DataRobot runs models at 16% (by default) of total data and advances the top 16 models, then runs those at 32%. Taking the top 8 models from that run, DataRobot runs on 64% of the data (or 500MB of data, whichever is smaller). See also Quick (Autopilot), Comprehensive, and Manual.

AutoTS (Automated time series)

A software system that automates all or most of the steps needed to build forecasting models, including featurization, model specification, model training, model selection, validation, and forecast generation. See also time series.

Average baseline

The average of the target in the Feature Derivation Window; used in time series modeling.



The time-aware equivalent of cross-validation. Unlike cross-validation, however, backtests allow you to select specific time periods or durations for your testing instead of random rows, creating “trials” for your data.

Baseline model

Also known as a naive model. A simple model used as a comparison point to confirm that a generated ML or time series model is learning with more accuracy than a basic non-ML model.

For example, generated ML models for a regression project should perform better than a baseline model that predicts the mean or median of the target. Generated ML models for a time series project should perform better than a baseline model that predicts the future using the most recent actuals (i.e., using today's actual value as tomorrow's prediction).

For time series projects, baseline models are used to calculate the MASE metric (the ratio of the MAE metric over the baseline model).

Batch predictions

A method of making predictions with large datasets, in which you pass input data and get predictions for each row; predictions are written to output files. Users can make batch predictions with MLOps via the Predictions interface or can use the Batch Prediction API for automating predictions. Schedule batch prediction jobs by specifying the prediction data source and destination and determining when the predictions will be run.

Bias Mitigation

Augments blueprints with a pre- or post-processing task intended to reduce bias across classes in a protected feature. Bias Mitigation is also a model Leadboard tab (Bias and Fairness > Bias Mitigation) where you can apply mitigation techniques after Autopilot has finished.

Bias vs Accuracy

A Leaderboard tab that generates a chart to show the tradeoff between predictive accuracy and fairness, removing the need to manually note each model's accuracy score and fairness score for the protected features.

"Blind History"

“Blind history," used in time-aware modeling, captures the gap created by the delay of access to recent data (e.g., “most recent” may always be one week old). It is defined as the period of time between the smaller of the values supplied in the Feature Derivation Window and the forecast point. A gap of zero means "use data up to, and including, today;" a gap of one means "use data starting from yesterday" and so on.


A model that potentially increases accuracy by combining the predictions of between two and eight models. DataRobot can be configured to automatically create blender models as part of Autopilot, based on the top three regular Leaderboard models (for AVG, GLM, and ENET blenders). You can also create blenders manually (aka ensemble models).


A graphical representation of the many steps involved in transforming input predictors and targets into a model. A blueprint represents the high-level end-to-end procedure for fitting the model, including any preprocessing steps, algorithms, and post-processing. Each box in a blueprint may represent multiple steps. You can view a graphical representation of a blueprint by clicking on a model on the Leaderboard. See also user blueprints.


"Can't operationalize" period

The "can't operationalize" period, used in time series modeling, defines the gap of time immediately after the Forecast Point and extending to the beginning of the Forecast Window. It represents the time required for a model to be trained, deployed to production, and to start making predictions—the period of time that is too near-term to be useful. For example, predicting staffing needs for tomorrow may be too late to allow for taking action on that prediction.


See AI Catalog.


The center of a cluster generated using unsupervised learning. A centroid is the multi-dimensional average of a cluster, where the dimensions are observations (data points).

CFDS (Customer Facing Data Scientist)

A DataRobot employee responsible for the technical success of user and potential users. They assist with tasks like structuring data science problems to complete integration of DataRobot. CFDS are passionate about ensuring user success.

Challenger models

Models that you can compare to a currently deployed model (the "champion" model) to continue model comparison post-deployment. Submit a challenger model to shadow a deployed model and replay predictions made against the champion to determine if there is a superior DataRobot model that would be a better fit.

Champion model

A model recommended by DataRobot—for a deployment (predictions) or for time series segmented modeling.

In MLOps, you can replace the champion selected for a deployment yourself or you can set up Automated Retraining, where DataRobot compares challenger models with the champion model and replaces the champion model if a challenger outperforms the champion.

In the segmented modeling workflow, DataRobot builds a model for each segment. DataRobot recommends the best model for each segment—the segment champion. The segment champions roll up into a Combined Model. For each segment, you can select a different model as champion, which is then used in the Combined Model.


The connection between an output port of one module and an input port of another module. Data flows from one module's output port to another module's input port via a channel, represented visually by a line connecting the two.


Sending prompts (and as a result, LLM payloads) to LLM endpoints based on a single LLM blueprint and receiving a response from the LLM. In this case, context from previous prompts/responses is sent along with the payload.


The action of taking a body of unstructured text and breaking it up into smaller pieces of unstructured text (tokens).


The chunks of text from the vector database used during the generation of LLM responses.


A type of prediction problem that classifies values into discrete, final outcomes or classes. Binary classification problems are those datasets in which what you are trying to predict can be one of two classes (for example, "yes" or "no"). Multiclass classification is a classification problem that results in more than two outcomes (for example, "buy", "sell", or "hold"). Unlimited multiclass is the ability to handle projects with a target feature containing an unlimited number of classes, with support for both a high threshold of individual classes and multiclass aggregation to support an unlimited number of classes above the threshold. See also regression.


A form of unsupervised learning used to group similar data and identify natural segments.


A model Leaderboard tab (Describe > Coefficients) that provides a visual indicator of information that can help you refine and optimize your models.

Combined Model

The final model generated in a time series segmented modeling workflow. With segmented modeling, DataRobot builds a model for each segment and combines the segment champions into a single Combined Model that you can deploy.

Common event

A data point is a common event if it occurs in a majority of weeks in data (for example, regular business days and hours would be common, but an occasional weekend data point would be uncommon).

Compliance documentation

Automated model development documentation that can be used for regulatory validation. The documentation provides comprehensive guidance on what constitutes effective model risk management.

Composable ML

A code-centric feature, designed for data scientists, that allows applying custom preprocessing and modeling methods to create a blueprint for model training. Using built-in and custom tasks, you can compose and then integrate the new blueprint with other DataRobot features to augment and improve machine learning pipelines.


A modeling mode that runs all Repository blueprints on the maximum Autopilot sample size to ensure more accuracy for models.

Computer vision

Use of computer systems to analyze and interpret image data, used with Visual AI. Computer vision tools generally use models that incorporate principles of geometry to solve specific problems within the computer vision domain. For example, computer vision models may be trained to perform object recognition (recognizing instances of objects or object classes in images), identification (identifying an individual instance of an object in an image), detection (detecting specific types of objects or events in images), etc.

Computer vision tools/techniques

Tools—for example, models, systems—that perform image preprocessing, feature extraction, and detection/segmentation functions.

Confusion matrix

A table that reports true versus predicted values. The name “confusion matrix” refers to the fact that the matrix makes it easy to see if the model is confusing two classes (consistently mislabeling one class as another class). The confusion matrix is available as part of the ROC Curve, Eureqa, and Confusion Matrix for multiclass model visualizations in DataRobot.

Connection instance

A connection that is configured with metadata about how to connect to a source system (e.g., instance of a Snowflake connection).


A central hub for deployment management activity. The dashboard provides access to deployed models for further monitoring, prediction activities, and mitigation.


A model Leaderboard tab (Describe > Constraints) that allows you to review monotonically constrained features if feature constraints were configured in Advanced Options prior to modeling.


Information used to authenticate and authorize actions against data connections. The most common connection is through username and password, but alternate authentication methods include LDAP, Active Directory, and Kerberos.

Cross-Class Accuracy

A model Leaderboard tab (Bias and Fairness > Cross-Class Accuracy) that helps to shows why the model is biased, and where in the training data it learned the bias from. Bias and Fairness settings must be configured.

Cross-Class Data Disparity

A model Leaderboard tab (Bias and Fairness > Cross-Class Data Disparity) that calculates, for each protected feature, evaluation metrics and ROC curve-related scores segmented by class. Bias and Fairness settings must be configured.


Also known as CV. A type of validation partition that is run to test (validate) model performance. Using subsets ("folds") of the validation data, DataRobot creates one model per fold, with the data assigned to that fold used for validation and the rest of the data used for training. By default, DataRobot uses five-fold cross-validation and presents the mean of those five scores on the Leaderboard. See also validation.

Custom inference models

User-created, pre-trained models uploaded as a collection of files via the Custom Model Workshop. Upload a model artifact to create, test, and deploy custom inference models to the centralized deployment hub in DataRobot. An inference model can have a predefined input/output schema or it can be unstructured. To customize prior to model training, use custom tasks.

Custom model workshop

In the Model Registry, a location where you can upload user-created, pre-trained models as a collection of files. You can use these model artifacts to create, test, and deploy custom inference models to centralized deployment hub in DataRobot.

Custom task

A data transformation or ML algorithm, for example, XGBoost or One-hot encoding, that can be used as a step in an ML blueprint inside DataRobot and used for model training. Tasks are written in Python or R and are added via the Custom Model Workshop. Once saved, the task can be used when modifying a blueprint with Composable ML. To deploy a pre-trained model where re-training is not required, use custom inference models.


See Cross Validation.


Data drift

The difference between values in new inference data used to generate predictions for models in production and the training data initially used to train the deployed model. Predictive models learn patterns in training data and use that information to predict target values for new data. When the training data and the production data change over time, causing the model to lose predictive power, the data surrounding the model is said to be drifting. Data drift can happen for a variety of reasons, including data quality issues, changes in feature composition, and even changes in the context of the target variable.

Data management

The umbrella term related to loading, cleaning, transforming, and storing data within DataRobot. It also refers to the practices that companies follow when collecting, storing, using, and deleting data.

Data preparation

The process of transforming raw data to the point where it can be run through machine learning algorithms to uncover insights or make predictions. Also called “data preprocessing,” this term covers a broad range of activities like normalizing data, standardizing data, statistically or mathematically transforming data, processing and/or preprocessing data, and feature engineering.

Data Quality Handling Report

A model Leaderboard tab (Describe > Data Quality Handling Report) that analyzes the training data and provides the following information for each feature: feature name, variable type, row count, percentage, and data transformation information.

Data Registry

In Workbench, a central catalog for datasets, allowing you to link them to specific Use Cases.

Data wrangling

Data preparation operations of a scope that ties to creating a dataset at an appropriate unit of analysis for a given machine learning use case.

DataRobot User Model (DRUM)

A tool that allows you to test Python, R, and Java custom models and tasks locally. The test allows you to verify that a custom model can successfully run and make predictions in DataRobot before uploading it.

DataRobot University (DRU)

Provides practical data science education to solve business problems. DRU offers guided learning, self-paced and instructor-led courses, and labs, as well as certification programs, across many topics and skill levels.


Data, a file or the content of a data source, at a particular point in time. A data source can produce multiple datasets; an AI Catalog dataset has exactly one data source. In AI Catalog, a dataset is materialized data that is stored with a catalog version record. There may be multiple catalog version records associated with an entity, indicating that DataRobot has reloaded or refreshed the data. The older versions are stored to support existing projects, new projects use the most recent version. A dataset can be in one of two states:

  • A "snapshotted" (or materialized) dataset is an immutable snapshot of data that has previously been retrieved and saved.
  • A “remote” (or unmaterialized) dataset has been configured with a location from which data is retrieved on-demand (AI Catalog).

Data connection

A configured connection to a database—it has a name, a specified driver, and a JDBC URL. You can register data connections with DataRobot for ease of re-use. A data connection has one connector but can have many data sources.

Data source

A configured connection to the backing data (the location of data within a given endpoint). A data source specifies, via SQL query or selected table and schema data, which data to extract from the data connection to use for modeling or predictions. Examples include the path to a file on HDFS, an object stored in S3, and the table and schema within a database. A data source has one data connection and one connector but can have many datasets. It is likely that the features and columns in a datasource do not change over time, but that the rows within change as data is added or deleted.

Data stage

Intermediary storage that supports multipart upload of large datasets, reducing the chance of failure when working with large amounts of data. Upon upload, the dataset is uploaded in parts to the data stage, and once the dataset is whole and finalized, it is pushed to the AI Catalog or Batch Predictions. At any time after the first part is uploaded to the data stage, the system can instruct Batch Predictions to use the data from the data stage to fill in predictions.

Data store

A general term used to describe a remote location where your data is stored. A data store may contain one or more databases, or one or more files of varying formats.

Data/time partitioning

The only valid partitioning method for time-aware projects. With date/time, rows are assigned to backtests chronologically instead of, for example, randomly. Backtests are configurable, including number, start and end times, and sampling method.

Deep learning

A set of algorithms that run data through several “layers” of neural network algorithms, each of which passes a simplified representation of the data to the next layer. Deep learning algorithms are essential to Visual AI capabilities, and their processing can be viewed from the Training Dashboard visualization.

Deploying (from a playground)

LLM blueprints and all their associated settings are registered in the Registry and can be deployed with DataRobot's production suite of products.

Deployment inventory

The central hub for managing deployments. Located on the Deployments page, the inventory serves as a coordination point for stakeholders involved in operationalizing models. From the inventory, you can monitor deployed model performance and take action as necessary, managing all actively deployed models from a single point.


A computer vision technique that involves the selection of a subset of the input image data for further processing (for example, one or more images within a set of images or regions within an image).

Downloads tab

A model Leaderboard tab (Predict > Downloads) where you can download model artifacts.


See Smart downsampling.


The software that allows the DataRobot application to interact with a database; each data connection is associated with one driver (created and installed by your administrator). The driver configuration saves the JAR file storage location in DataRobot and any additional dependency files associated with the driver. DataRobot supports JDBC drivers.

Dynamic dataset

A dynamic dataset is a "live" connection to the source data, however, DataRobot samples the data for profile statistics (EDA1). The catalog stores a pointer to the data and pulls it upon request, for example, when you create a project.


EDA (Exploratory Data Analysis)

The DataRobot approach to analyzing and summarizing the main characteristics of a dataset. Generally speaking, there are two stages of EDA:

  • EDA1 provides summary statistics based on a sample of data. In EDA1, DataRobot counts, categorizes, and applies automatic feature transformations (where appropriate) to data.
  • EDA2 is a recalculation of the the statistics collected in EDA1 but using the entire dataset, excluding holdout. The results of this analysis are the criteria used for model building.


A numerical (vector) representation of text, or a collection of numerical representations of text. The action of generating embeddings means taking a chunk of unstructured text and using a text embedding model to convert the text to a numerical representation. The chunk is the input to the embedding model and the embedding is the “prediction” or output of the model.

Ensemble models

See blender.


A Docker container where a custom task runs.


Exploratory Spatial Data Analysis (ESDA) is the exploratory data phase for Location AI. DataRobot provides a variety of tools for conducting ESDA within the DataRobot AutoML environment, including geometry map visualizations, categorical/numeric thematic maps, and smart aggregation of large geospatial datasets.


Model blueprints for Eureqa generalized additive models (Eureqa GAM), Eureqa regression, and Eureqa classification models. These blueprints use a proprietary Eureqa machine learning algorithm to construct models that balance predictive accuracy against complexity.

EWMA (Exponentially Weighted Moving Average)

A moving average that places a greater weight and significance on the most recent data points, measuring trend direction over time. The "exponential" aspect indicates that the weighting factor of previous inputs decreases exponentially. This is important because otherwise a very recent value would have no more influence on the variance than an older value.


An asset of a Use Case that is the result of having run the DataRobot modeling process. A Use Case can have zero or more experiments.

Exploratory data insights

See EDA.

External stage

An external stage is a cloud location outside of the Snowflake environment used for loading and unloading data for Snowflake. The cloud location can be either Amazon S3 or Microsoft Azure storage.


Fairness score

A numerical computation of model fairness against the protected class, based on the underlying fairness metric.

Fairness Threshold

The measure of whether a model performs within appropriate fairness bounds for each protected class. It does not affect the fairness score or performance of any protected class.

Fairness Value

Fairness scores normalized against the most favorable protected class (i.e., the class with the highest fairness score).

Favorable Outcome

A value of the target that is treated as the favorable outcome for the model, used in bias and fairness modeling. Predictions from a binary classification model can be categorized as being a favorable outcome (i.e., good/preferable) or an unfavorable outcome (i.e., bad/undesirable) for the protected class.


See Feature Derivation Window.


A column in a dataset, also called "variable" or "feature variable." The target feature is the name of the column in the dataset that you would like to predict.

Feature Derivation Window

Also known as FDW; used in time series modeling. A rolling window of past values that models use to derive features for the modeling dataset. Consider the window relative to the Forecast Point, it defines the number of recent values the model can use for forecasting.

Feature Discovery

A DataRobot capability that discovers and generates new features from multiple datasets, eliminating the need to perform manual feature engineering to consolidate multiple datasets into one. A relationship editor visualizes these relationships and the end product is additional, derived features that result from the created linkages.

Feature Effects

A model Leaderboard tab (Understand > Feature Effects) that shows the effect of changes in the value of each feature on the model’s predictions. It displays a graph depicting how a model "understands" the relationship between each feature and the target, with the features sorted by Feature Impact.

Feature engineering

The generation of additional features in a dataset, which as a result, improve model accuracy and performance. Time series and Feature Discovery both rely on feature engineering as the basis of their functionality.

Feature extraction

Models that perform image preprocessing (or image feature extraction and image preprocessing) are also known as “image feature extraction models” or “image-specific models.”

Feature Extraction and Reduction (FEAR)

The feature generation process for time series modeling (e.g., lags, moving averages). It extracts new features (now) and then reduces the set of extracted features (later). See time series feature derivation.

Feature Impact

A measurement that identifies which features in a dataset have the greatest effect on model decisions. In DataRobot, the measurement is reported as a visualization available from the Leaderboard.

Feature imputation

A mechanism in time series modeling that uses forward filling to enable imputation for all features (target and others) when using the time series data prep tool. This results in a dataset with no missing values (with the possible exception of leading values at the start of each series where there is no value to forward fill).

Feature list

A subset of features from a dataset used to build models. DataRobot creates several lists during EDA2 including all informative features, informative features excluding those with a leakage risk, a raw list of all original features, and a reduced list. Uses can create project-specific lists as well.


See model fitting.

Forecast Distance

A unique time step—a relative position—within the Forecast Window in a time series modeling project. A model outputs one row for each Forecast Distance.

Forecast Point

In time series modeling, the point you are making a prediction from; a relative time "if it was now..."; DataRobot trains models using all potential forecast points in the training data. In production, it is typically the most recent time.

Forecast vs Actual

A model Leaderboard tab (Evaluate > Forecast vs Actual) commonly used in time series projects that allows you to compare how different predictions behave from different forecast points to different times in the future. Although similar to the Accuracy Over Time chart, which displays a single forecast at a time, the Forecast vs Actual chart shows multiple forecast distances in one view.

Forecast Window

Also known as FW; used in time series modeling. Beginning from the Forecast Point, defines the range (the Forecast Distance) of future predictions—"this is the range of time I care about." DataRobot then optimizes models for that range and ranks them on the Leaderboard on the average across that range.


Predictions based on time, into the future; use inputs from recent rows to predict future values. Forecasting is a subset of predictions, using trends in observation to characterize expected outcomes or expected responses.

Foundation model

A type of artificial intelligence model that is pre-trained on a broad range of Internet text. Examples of text foundation models are GPT-4 and PaLM. These models are referred to as “foundation” because they can be fine-tuned for a wide variety of specific tasks, much like how a foundation supports a range of structures above it.

Frozen run

A process that “freezes” parameter settings from a model’s early, small sample size-based run. Because parameter settings based on smaller samples tend to also perform well on larger samples of the same data.


See Forecast Window.


Generative AI

A type of artificial intelligence that leverages trained models to generate new content or data that is based on the training data. Generative AI can generate text, images, audio, and even code. The key difference is that outputs are created based on prompting rather than analysis and processing of input features. Generative AI incorporates any novel technologies including transformers, LLMs (large language models,) and GANs (generative adversarial networks).

Governance lens

A filtered view of DataRobot's deployment inventory on the Deployments page, summarizing the social and operational aspects of a deployment. These include the deployment owner, how the model was built, the model's age, and the humility monitoring status.

GPU (graphics processing unit)

A mechanism for processing computational tasks. GPUs are GPUs are highly optimized to do mathematical calculations and great at parallelism, but only for less complex tasks. Deep learning specifically benefits from that since it's mainly batches of matrix multiplication, and these can be parallelized very easily.

An exhaustive search method used for hyperparameters.



A subset of data that is unavailable to models during the training and validation process. Use the Holdout score for a final estimate of model performance only after you have selected your best model. See also Validation.


A user-defined set of rules for deployments that allow models to be capable of recognizing, in real-time, when they make uncertain predictions or receive data they have not seen before. Unlike data drift, model humility does not deal with broad statistical properties over time—it is instead triggered for individual predictions, allowing you to set desired behaviors with rules that depend on different triggers.


Image data

A sequence of digital images (e.g., video), a set of digital images, a single digital image, and/or one or more portions of any of these—data used as part of Visual AI. A digital image may include an organized set of picture elements (“pixels”) stored in a file. Any suitable format and type of digital image file may be used, including but not limited to raster formats (e.g., TIFF, JPEG, GIF, PNG, BMP, etc.), vector formats (e.g., CGM, SVG, etc.), compound formats (e.g., EPS, PDF, PostScript, etc.), and/or stereo formats (e.g., MPO, PNS, JPS).

Image preprocessing

A computer vision technique, part of Visual AI. Some examples include image re-sampling, noise reduction, contrast enhancement, and scaling (e.g., generating a scale space representation). Extracted features may be:

  • Low-level: raw pixels, pixel intensities, pixel colors, gradients, textures, color histograms, motion vectors, edges, lines, corners, ridges, etc.
  • Mid-level: shapes, surfaces, volumes, etc.
  • High-level: objects, scenes, events, etc.

Inference data

Data that is scored by applying an algorithmic model built from a historical dataset in order to uncover practical insights. See also Scoring data.

In-sample predictions

Models trained on data outside of the training set (i.e., Validation and potentially Holdout). DataRobot uses 64% of the training set by default. When models are trained with a sample size above 64%, DataRobot marks the Validation score with an asterisk to indicate that some in-sample predictions were used for that score. If you train above 80%, the Holdout score is also asterisked. Compare to stacked (out-of-sample) predictions.

Irregular data

Data in which no consistent spacing and no time step is detected. Used in time-aware modeling.



See Known in advance features.

Known in advance features

Also known as KA; used in time series modeling. A variable for which you know the value in advance and does not need to be lagged, such as holiday dates. Or, for example, you might know that a product will be on sale next week and so you can provide the pricing information in advance.


Large language model (LLM)

An algorithm that uses deep learning techniques and large datasets to understand, summarize, generate, and predict new content.


The list of trained blueprints (models) for a project, ranked according to a project metric.

Linkage keys

(Feature Discovery) The features in the primary dataset used as keys to join and create relationships.

LLM blueprint

The saved blueprint, available to be used for deployment. LLM blueprints represent the full context for what is needed to generate a response from an LLM; the resulting output can be compared within the playground. This information is captured in the LLM blueprint settings.

LLM blueprint components

The entities that make up the LLM blueprint settings, this refers to the vector database, embedding model user to generate the vector database, LLM settings, system prompt, etc. These components can either be offered natively within DataRobot or can be brought in from external sources.

LLM blueprint settings

The parameters sent to the LLM to generate a response (in conjunction with the user-entered prompt). They include a single LLM, LLM settings, optionally a system prompt, and optionally a vector database. If no vector database is assigned, then the LLM uses its learnings from training to generate a response. LLM blueprint settings are configurable so that you can experiment with different configurations.

LLM payload

The bundle of contents sent to the LLM endpoint to generate a response. This includes the user prompt, LLM settings, system prompt, and information retrieved from the vector database.

LLM responses

Generated text from the LLM based on the payload sent to an LLM endpoint.

LLM settings

Parameters that define how an LLM intakes a user prompt and generates a response. They can be adjusted within the LLM blueprint to alter the response. These parameters are currently represented by the "Temperature", "Token selection probability cutoff (Top P)", and "Max completion tokens" settings.

Location AI

A trained ML pipeline, capable of scoring new data. Models—descriptive, predictive, prescriptive—form the basis of data analysis. Modeling extracts insights from data that you can then use to make better business decisions. Algorithmic models tell you which outcome is likely to hold true for your target variable based on your training data. They construct a representation of the relationships and tease out patterns between all the different features in your dataset that you can apply to similar data you collect in the future, allowing you to make decisions based on those patterns and relationships.

Model Comparison

A Leaderboard tab that allows you to compare two models using different evaluation tools, helping identify the model that offers the highest business returns or candidates for blender models.

Model fitting

A measure of how well a model generalizes similar data to the data on which it was trained. A model that is well-fitted produces more accurate outcomes. A model that is overfitted matches the data too closely. A model that is underfitted doesn’t match closely enough.

The place where you create and interact with LLM blueprints (LLMs and their associated settings), comparing the response of each to help determine which to use in production. Many LLM blueprints can live within a playground. A playground is an asset of a Use Case; multiple playgrounds can exist in a single Use Case.

Playground compare

The place to add LLM blueprints to the playground for comparison, submit prompts to these LLM blueprints, and evaluate the rendered responses. With RAG, a single prompt is sent to an LLM to generate a single response, without referencing previous prompts. This allows users to compare responses from multiple LLM blueprints.

Portable Prediction Server (PPS)

A DataRobot execution environment for DataRobot model packages (.mlpkg files) distributed as a self-contained Docker image. It can be run disconnected from main installation environments.


For non-time-series modeling. Use information in a row to determine the target for that row. Prediction uses explanatory variables to characterize expected outcomes or expected responses (e.g., a specific event in the future, gender, fraudulent transactions).

Prediction environment

An environment configured to manage deployment predictions on an external system, outside of DataRobot. Prediction environments allow you to configure deployment permissions and approval processes. Once configured, you can specify a prediction environment for use by DataRobot models running on the Portable Prediction Server and for remote models monitored by the MLOps monitoring agent.

Prediction Explanations

A visualization that helps to illustrate what drives predictions on a row-by-row basis—they provide a quantitative indicator of the effect variables have on a model, answering why a given model made a certain prediction. It helps to understand why a model made a particular prediction so that you can then validate whether the prediction makes sense. See also SHAP, XEMP.

Prediction intervals

Prediction intervals help DataRobot assess and describe the uncertainty in a single record prediction by including an upper and lower bound on a point estimate (e.g., a single prediction from a machine learning model). The prediction intervals provide a probable range of values that the target may fall into on future data points.

Prediction point

The point in time when you made or will make a prediction. Plan your prediction point based on the production model (for example, “one month before renewal” or “loan application submission time”). Once defined, create that entry in the training data to help avoid lookahead bias. With Feature Discovery, you define the prediction point to ensure the derived features only use data prior to that point.

SHAP (Shapley Values)

A fast, open-source methodology for computing Prediction Explanations for tree-based, deep learning, and linear-based models. SHAP estimates how much each feature contributes to a given prediction differing from the average. It is additive, making it easy to see how much top-N features contribute to a prediction. See also Prediction Explanations, XEMP.

Sidecar model

A structural component that supports the LLM that is serving back responses. It helps to make determinations about whether a prompt was toxic, an injection attack, etc. With DataRobot, it uses hosted custom metrics to accomplish the monitoring.

Smart downsampling

A technique to reduce total dataset size by reducing the size of the majority class, enabling you to build models faster without sacrificing accuracy. When enabled, all analysis and model building is based on the new dataset size after smart downsampling.


An asset created from a data source. For example, with a database it represents either the entire database or a selection of (potentially joined) tables, taken at a particular point in time. It is taken from a live database but creates a static, read-only copy of data. DataRobot creates a snapshot of each data asset type, while allowing you to disable the snapshot when importing the data.

Stacked predictions

A method for building multiple models on different subsets of the data. The prediction for any row is made using a model that excluded that data from training. In this way, each prediction is effectively an “out-of-sample” prediction. See an example in the predictions documentation. Compare to "in-sample" predictions.


The mean of the series does not change over time. A stationary series does not have a trend or seasonal variation. Applicable to time series modeling. See also trend.

System prompt

The system prompt, an optional field, is a "universal" prompt prepended to all individual prompts. It instructs and formats the LLM response. The system prompt can impact the structure, tone, format, and content that is created during the generation of the response.



The name of the column in the dataset that you would like to predict.

Target leakage

An outcome when using a feature whose value cannot be known at the time of prediction (for example, using the value for “churn reason” from the training dataset to predict whether a customer will churn). Including the feature in the model’s feature list would incorrectly influence the prediction and can lead to overly optimistic models.

Time series analysis

Methods for analyzing time series data in order to extract meaningful statistics and other characteristics of the data.

Time series forecasting

The use of a model to predict future values based on previously observed values. In practice, a forecasting model may combine time series features with other data.

Time step

The detected median time delta between rows in the time series; DataRobot determines the time unit. The time step consists of a number and a time-delta unit, for example (15, “minutes”). If a step isn’t detected, the dataset is considered irregular and time series mode may be disabled. See also regular data and semi-regular data.


A token is the smallest unit of text an LLM can work with. When processing a user prompt, the LLM splits the input text into tokens and generates the output token by token. Different LLMs can separate the same text into tokens differently as they learn their vocabulary from the data they were trained on. Depending on the language and the LLM, a token can be a character, a group of characters, a word, or any other unit of text. An approximation of token length for GPT models is 1 token ~= 4 chars in English.

Unstructured text

Text that cannot fit cleanly into a table. The most typical example is large blocks of text typically in some kind of document or form.

Unsupervised learning

The ability to infer patterns from a dataset without reference to known (labeled) outcomes and without a specified target. Types of unsupervised learning include anomaly detection, outlier detection, novelty detection, and clustering. With anomaly detection, DataRobot applies unsupervised learning to detect abnormalities in a dataset. With clustering, DataRobot uses unsupervised learning to discern natural groupings in the data. See also supervised learning.

Use Case

A container that groups objects that are part of the Workbench experimentation flow.

User blueprint

A blueprint (and extra metadata) that has been created by a user and saved to the AI Catalog, where it can be both shared and further modified. This is not the same as a blueprint available from the Repository or via models on the Leaderboard, though both can be used as the basis for creation of a user blueprint. See also blueprint.



The validation (or testing) partition is a subsection of data that is withheld from training and used to evaluate a model’s performance. Since this data was not used to build the model, it can provide an unbiased estimate of a model’s accuracy. You often compare the results of validation when selecting a model. See also cross-validation.


See feature.

Vector database

A collection of chunks of unstructured text and corresponding text embeddings for each chunk, indexed for easy retrieval. Vector databases can optionally be used to ground the LLM responses to specific information and can be assigned to an LLM blueprint to leverage during a RAG operation. The creation of a vector database occurs when a collection of unstructured text is broken up into chunks, embeddings are generated for each chunk, and both the chunks and embeddings are stored in a database and are available for retrieval by some service. Updating the vector database is the action of adding (or removing) content to (or from) the originally created vector database. This means adding new chunks of text (or removing) and creating new embeddings (or removing) in the vector database.
