In the spotlight...

The following features are some of the highlights of Release 7.1:

New documentation experience

This release introduces a new documentation experience for DataRobot platform application users.

In addition to a new look, the organization has been modified to better reflect the end-to-end modeling workflow. Content has been added—and moved—to provide easier access to documentation resources. Specifically:

  • Content changes:

    • DataRobot Data Prep documentation, while also available at the legacy location, can now be accessed from the platform site.
    • A DataRobot glossary, which will grow over time, is available.
    • API documentation—a Quickstart and REST API, Python client, and R client documentation—can be launched from within the site.
  • Zoom images for a closer look. When you hover on an image, a magnifier appears. Click once on the image to expand it in-screen, click again to return to the page.

  • Book (left-side) and page-specific (right side) table of contents make navigation easier.

The site will continue to grow, with notebook and tutorial content coming soon. Questions, comments, and suggestions are welcome, send email to docs@datarobot.com.

Automated AI reports

With this release, you can now create and download the DataRobot AI report—documentation that provides a high-level overview of the modeling building process.

The report summarizes the most important findings of a project, allowing you to present them to stakeholders in an easily consumable format. It provides accuracy insights for the top-performing model, including speed and cross-validation scores. It also captures interpretability insights from the Feature Impact histogram for your top-performing model. Detailed model explanations, performance metrics, and ethics insights generated in the AI Report help you build overall trust in your AI projects and prove value to your key stakeholders.

Feature Discovery Snowflake integration

An integration between DataRobot and Snowflake allows joint users to execute Feature Discovery projects in DataRobot while performing computations in Snowflake, when beneficial. The integration minimizes data movement, making the computation of new model features faster, more accurate, and more cost-effective. DataRobot detects whether all secondary datasets configured for the project are dynamic and are referencing tables in Snowflake. If they are, DataRobot automatically pushes joins and filtering operations into Snowflake, and then loads the smaller result set back into DataRobot. Because Feature Discovery is now starting with smaller datasets, DataRobot project runtimes are reduced.

Beta: Purpose-built AI applications with the AI App Builder

The AI App Builder provides a way for users without coding experience to launch, configure, and share AI-powered applications in a visual and interactive interface so that predictions can be easily shared and consumed—optimizing decision-making for a machine learning use case and delivering increased value from data.

Similar to apps deployed from the Application Gallery, each application starts with an application type and data source—either a deployment or dataset in the AI Catalog. However, in the App Builder, you can then configure additional widgets, custom features, and pages to tailor the application to a specific use case.

In Applications > Current Applications, you can view a list of existing applications and click + Create Application to create a new one in the AI App Builder.

In edit mode, create pages to organize your insights, then drag-and-drop header and chart widgets to tailor the application to a specific use case.

New AutoML features and enhancements

The following list the new AutoML features in release v7.1.0, described below.

  • Keras-specific training dashboard
  • Feature Discovery now supports anomaly detection
  • New blueprints and Advanced Tuning parameters for image datasets
  • Support for dynamic Spark SQL in Feature Discovery
  • Tiny BERT pretrained featurizer implementation extends NLP
  • Model compliance documentation for multiclass projects
  • Improved Eureqa training behavior
  • Beta: Feature Discovery relationship quality assessment

Keras-specific training dashboard

The Training Dashboard tab provides, for each executed candidate model, visualizations of varying hyperparameters over time. In other words, it helps to understand what happened during model training, and how well the model fits the data. The tab provides visualization in areas of training and test loss, accuracy, learning rate, and momentum across all iterations. Select candidate models to compare and modify settings to change the displays and help interpretability.

Use the information found in this tab to inform decisions about which parameters to tune in order to improve the final model. From the dashboard you can assess the impact that each parameter has on model performance, and with direct links to the Advanced Tuning tab, you can further tune and test the model.

Feature Discovery now supports anomaly detection

Now GA: Now available, you can leverage Feature Discovery's secondary dataset capabilities to detect anomalies. When unsupervised learning (i.e., no target) is enabled, and you add a secondary dataset, Feature Discovery will extract features from the secondary datasets to help detect anomalies, removing the need to script feature engineering outside of DataRobot.

New blueprints and Advanced Tuning parameters for image datasets

This release makes available fine-tuning of Deep Learning convolutional neural network (CNN) with pretrained architecture blueprints. Training a CNN on a small dataset greatly affects the deep convolutional network’s ability to generalize, often resulting in overfitting. Fine-tuning is a process that takes a pretrained network model and applies it to a second similar task, while still allowing further customization of the layer's trainable scope and learning rate. Fine-tuning will often improve the performance and accuracy of a CNN when the project is large and drastically different in context from the pretrained dataset. At times it even outperforms the base pretrained CNN featurizer in small datasets that are close in context from the pretrained dataset. From the Training Dashboard you can investigate metric scores, learning rates of each layer, and general learning rates of each iteration.

Support for dynamic Spark SQL in Feature Discovery

Now GA: For Feature Discovery secondary datasets, DataRobot offers the ability to enrich, transform, shape, and blend together snapshotted datasets using Spark SQL queries from within the AI Catalog. First introduced as a beta feature, and now generally available, DataRobot adds support for dynamic Spark SQL in secondary datasets for Feature Discovery projects. This new functionality increases flexibility in performing basic data prep. Authentication requirements remain the same.

Tiny BERT pretrained featurizer implementation extends NLP

Now GA: BERT (Bidirectional Encoder Representations from Transformers) is Google's transformer-based de-facto standard for natural language processing (NLP) transfer learning. Tiny BERT (or any distilled, smaller, version of BERT) is now available with certain blueprints in the DataRobot Repository. These blueprints provide pretrained feature extraction in the NLP field, similar to Visual AI featurizers with no fine-tuning needed. However, for maximum flexibility, DataRobot's implementation offers two additional tunable pooling parameters—Max Pooling and Average Pooling. Tiny BERT blueprints are available for both UI and API users.

Model compliance documentation for multiclass projects

The model compliance documentation, which allows users to automatically generate and download documentation that assists with deploying models in highly regulated industries, now supports multiclass models. If available for your organization, you can generate, for each model, individualized documentation to provide comprehensive guidance on what constitutes effective model risk management. Then, you can download the report as an editable Microsoft Word document (.docx). Previously only available for regression and classification, you can now include this documentation for projects with up to 100 classes. Access the option to build the model compliance documentation from a model’s Compliance tab on the project Leaderboard.

Improved Eureqa training behavior

With this release, new Eureqa blueprints have been added that use 250 generations (providing comparable accuracy to 1000 generations) for GAM and classic Eureqa models. The addition of these 250-generation blueprints increases the types of projects that will automatically include Eureqa as part of Autopilot (available as part of full, not quick). Other Eureqa generation-count models are still available from the Repository. See the Eureqa documentation for details on when and which models are available for AutoML and time series projects.

Beta: Feature Discovery relationship quality assessment

Introduced as a beta feature with this release, Feature Discovery introduces a tool to automatically assess the quality of a relationship configuration—warn the user of potential problems—early in the creation process. The tool verifies join keys, dataset selection, and time-aware settings. Before EDA2 begins:

Click the Review configuration button to trigger the relationship quality assessment. A progress indicator (loading spinner) displays on each dataset and on the review configuration button, which is disabled, to indicate that an assessment is currently running. Once the assessment is complete, DataRobot marks all tested datasets. Those with identified issues display a yellow warning icon and those with no identified issues display a green tick.

Select the dataset to view a summary of the issues with suggested potential fixes.

API enhancements

The following is a summary of API new features and enhancements. See the API Support page for API Documentation on each client.
