3.16.13 Model Types

HeatWave AutoML supports the following training models. When training a model, use the ML_TRAIN model_list and exclude_model_list options to specify the training models to consider or exclude. Section 3.14.1.3, “Model Metadata” includes the algorithm_name field which defines the model type.

Forecasting Models

Univariate endogenous models:

• NaiveForecaster

Anomaly Detection Models

The only model is GkNN. See: Section 3.10, “Anomaly Detection”.

Recommendation Models

Recommendation models that rate users or items to use with explicit feedback:

• Baseline
