ModelTrainer
Multithreaded LDA model trainer class, which primarily operates by running a "map/reduce"
operation, all in memory locally (ie not a hadoop job!) : the "map" operation is to take
the "read-only"
TopicModel and use it to iteratively learn the p(topic|term, doc)
distribution for documents (this can be done in parallel across many documents, as the
"read-only" model is, well, read-only. |
TopicModel
Thin wrapper around a
Matrix of counts of occurrences of (topic, term) pairs. |
