Crf inference
Webproposed a joint training of a MRF/CRF model together with an inference algorithm in their Active Random Field approach. Domke [14] advocated back-propagation based parameter optimization in graphical models when approxi-mate inference methods such as mean-field and belief prop-agation are used. This idea was utilized in [26], where a bi- Web2 days ago · For the CRF layer I have used the allennlp's CRF module. Due to the CRF module the training and inference time increases highly. As far as I know the CRF layer should not increase the training time a lot. Can someone help with this issue. I have tried training with and without the CRF. It looks like the CRF takes more time. pytorch.
