Fractional Kneser Ney

JosefNovak - 09 Oct 2012 - 04:31

Hi, I have been using OpenGrm with my Grapheme-to-Phoneme conversion tools for a while now and recently added some functionality to output weighted alignment lattices in .far format.

It is my understanding that these weighted lattices can only currently be utilized with Witten-Bell smoothing; is this correct?

Is there any plan to support fractional counts with Kneser-Ney smoothing, for instance along the lines of,

"Correlated Bigram LSA for Unsupervised Language Model Adaptation", Tam and Schultz.

or would I be best advised to implement this myself?
