Parameters: * ``iter``: number of iterations. * ``k``: number of topics. * ``d``: corpus.

val train : lda_typ -> model -> unit

After calling ``init``, calling this function starts the training.

Helper functions
val show_info : model -> int -> float -> unit

Function for printing out log information, tailored for LDA training.

val include_token : model -> int -> int -> int -> unit

Include a token in model, used in training and you are not supposed to use it.

val exclude_token : model -> int -> int -> int -> unit

Exclude a token in model, used in training and you are not supposed to use it.
