epic.sequences

CRF

trait CRF[L, W] extends Serializable

A -Markov Linear Chain Conditional Random Field. Useful for POS tagging, etc.

As usual in Epic, all the heavy lifting is done in the companion object and Marginals.

CRFs can produce epic.sequences.TaggedSequence from an input sequence of words. They can also produce marginals, etc.
