LDAOptimizer	initialize(RDD<scala.Tuple2<Object,Vector>> docs, LDA lda) Initializer for the optimizer.
LDAOptimizer	next()

Method Detail

getLDAModel

LDAModel getLDAModel(double[] iterationTimes)

initialize

LDAOptimizer initialize(RDD<scala.Tuple2<Object,Vector>> docs,
                        LDA lda)

Initializer for the optimizer. LDA passes the common parameters to the optimizer and the internal structure can be initialized properly.

Parameters:

docs - (undocumented)

lda - (undocumented)

Returns:

(undocumented)

next

LDAOptimizer next()
