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>

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 least one column contains strings. Validate _vecSize, windowSize, sentSampleRate, initLearningRate, and epochs for values within range.

Overrides:

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