Modeling algorithms

DataRobot supports a comprehensive library of pre- and post-processing (modeling) steps, which combine to make up the model blueprint. Which are run or available in the model repository is dependent on the dataset. The comprehensive combination of pre- and post-processing steps allows DataRobot to confidently create a Leaderboard of your best modeling options. Some examples of the modeling flexibility include logistic regression with and without PCA as a pre-processor or random forests with and without a greedy search for interaction terms.

The implication of this is that for every model in the list below, DataRobot likely runs two-to-five times, each with a different pre-processing and/or variable selection. The following sections list the relevant algorithms:
