Method Detail

can_build

public hex.ModelCategory[] can_build()

Specified by:

can_build in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>

builderVisibility

public hex.ModelBuilder.BuilderVisibility builderVisibility()

Overrides:

builderVisibility in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>

isSupervised

public boolean isSupervised()

Specified by:

isSupervised in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>

trainModelImpl

protected hex.word2vec.Word2Vec.Word2VecDriver trainModelImpl()

Specified by:

trainModelImpl in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>

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();". Verify that at the first column contains strings. Validate _vec_size, _window_size, _sent_sample_rate, _init_learning_rate, and epochs for values within range.

Overrides:

init in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>

ignoreBadColumns

protected void ignoreBadColumns(int npredictors,
                    boolean expensive)

Overrides:

ignoreBadColumns in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>

haveMojo

public boolean haveMojo()

Overrides:

haveMojo in class hex.ModelBuilder<Word2VecModel,Word2VecModel.Word2VecParameters,Word2VecModel.Word2VecOutput>
