Question about CRF model

[TompsonL]

Hi ,

Can I use the crfsuite to implement the model in the attached image? Thanks a lot.

If you can extract a "sequence" from your image, and expect sequence labels + one global label, I suggest you to look at TriCRF instead.
https://github.com/minwoo/TriCRF

The implemented model by TriCRF is:

       y
  /    |   \
h  -   h  -  h
|      |     |
x      x     x

The sequence labels as well as the global image label must be discrete.

Thanks for your response. Looks the h nodes in TriCRF are in a chain, Can I use a full connected ?

@TompsonL In principle yes, in practice inference in such graphs would be ahem difficult. Even this triangular chain CRF is fairly expensive (the way it is implemented). Unfortunately I am not familiar well enough with graphical models to suggest or make bigger claims.

@TompsonL I would try out a neural architecture - sequence model as for NER for "h" and classification on top of that for "y".

Thanks for your effort.
