Method Detail

logMe

protected boolean logMe()

Overrides:

logMe in class ModelBuilder<QuantileModel,QuantileModel.QuantileParameters,QuantileModel.QuantileOutput>

trainModelImpl

public ModelBuilder.Driver trainModelImpl()

Description copied from class: ModelBuilder

Model-specific implementation of model training

Specified by:

trainModelImpl in class ModelBuilder<QuantileModel,QuantileModel.QuantileParameters,QuantileModel.QuantileOutput>

Returns:

A F/J Job, which, when executed, does the build. F/J is NOT started.

can_build

public hex.ModelCategory[] can_build()

Description copied from class: ModelBuilder

List containing the categories of models that this builder can build. Each ModelBuilder must have one of these.

Specified by:

can_build in class ModelBuilder<QuantileModel,QuantileModel.QuantileParameters,QuantileModel.QuantileOutput>

desiredChunks

protected int desiredChunks(Frame original_fr,
                boolean local)

Description copied from class: ModelBuilder

Find desired number of chunks. If fewer, dataset will be rebalanced.

Overrides:

desiredChunks in class ModelBuilder<QuantileModel,QuantileModel.QuantileParameters,QuantileModel.QuantileOutput>

Returns:

Lower bound on number of chunks after rebalancing.

init

public void init(boolean expensive)

Initialize the ModelBuilder, validating all arguments and preparing the training frame. This call is expected to be overridden in the subclasses and each subclass will start with "super.init();". This call is made by the front-end whenever the GUI is clicked, and needs to be fast; heavy-weight prep needs to wait for the trainModel() call. Validate the probs.

Overrides:

init in class ModelBuilder<QuantileModel,QuantileModel.QuantileParameters,QuantileModel.QuantileOutput>
