    LDA training

    LDA training

    docs

    RDD of documents, which are term (word) count vectors paired with IDs. The term count vectors are "bags of words" with a fixed-size vocabulary (where the vocabulary size is the length of the vector). Document IDs must be unique and >= 0.

    totalIter

    the number of iterations

    numTopics

    the number of topics (5000+ for large data)

    alpha

    recommend to be (5.0 /numTopics)

    beta

    recommend to be in range 0.001 - 0.1

    alphaAS

    recommend to be in range 0.01 - 1.0

    useLightLDA

    use LightLDA sampling algorithm or not, recommend false for short text
