Citation for crf layer - Githubissues

siebeniris commented 6 years ago

Hi, I am doing my bachelor thesis. I want to use the equation of the likelihood function in https://github.com/keras-team/keras-contrib/blob/master/keras_contrib/layers/crf.py, is there a paper I can cite?

Thanks.

Digging around, I actually found this three papers which are about Conditional Neural Fields/Neural Sequence Labeling with CRF

Conditional Neural Fields - https://research.cs.washington.edu/istc/lfb/paper/nips09b.pdf
Sequential Labeling Using Deep-Structured Conditional Random Fields - https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5570918
(This paper which uses a Recurrent CRF) Using Recurrent Neural Networks for Slot Filling in Spoken Language Understanding - http://www.iro.umontreal.ca/~lisa/pointeurs/taslp_RNNSLU_final_doubleColumn.pdf

I didn't have the time to check if any of these report the same exact formalisation of what is implemented in the keras-contrib crf layer. Maybe the authors can give us a hint on this.
