SparseGenerativeModel (3.7)

Generative models for scalable text mining

Provides sparse matrix implementations for Multinomial Naive Bayes and Multinomial Kernel Density classifiers.Uses hash tables for training, inverted indices for classification.

Implements several options for smoothing, TF-IDF feature transforms, parameter pruning and model-based feedback.Default options smooth class-conditionals using Uniform Jelinek-Mercer and instance-conditionals with Pitman-Yor Process smoothing.

Restart Weka after package installation.

For preprocessing use Weka StringToWordVector with outputWordCounts=True.
