Are transition features conditioned on observations supported? #122

Open Rajon010 opened 2 years ago

Rajon010 commented 2 years ago

In the change log http://www.chokkan.org/software/crfsuite/ , I find

this is an initial attempt for implementing CRFs with different feature types (e.g., 2nd-order CRF, 1st-order transition features conditioned on observations)

However, here http://www.chokkan.org/software/crfsuite/manual.html I find

transition features are not conditioned on observations

and

State features are conditioned on combinations of attributes and labels, and transition features are conditioned on label bigrams.

Are transition features conditioned on observations supported now?
