WebUses viterbi algorithm to find most likely tags for the given inputs. If constraints are applied, disallows all other transitions. Returns a list of results, of the same size as the batch (one result per batch member) Each result is a List of length top_k, containing the top K viterbi decodings Each decoding is a tuple (tag_sequence, viterbi_score) WebThe software provides a general implementation of (arbitrary order) linear chain Conditional Random Field (CRF) sequence models. That is, by training your own models on labeled data, you can actually use this code to build sequence models for NER or any other task. ... For general use and support questions, you're better off joining and using ...

Conditional random fields (CRFs) are a class of statistical modeling methods often applied in pattern recognition and machine learning and used for structured prediction. Whereas a classifier predicts a label for a single sample without considering "neighbouring" samples, a CRF can take context into account. To do so, the predictions are modelled as a graphical model, which represents the pre… WebFor this section, we will see a full, complicated example of a Bi-LSTM Conditional Random Field for named-entity recognition. The LSTM tagger above is typically sufficient for part-of-speech tagging, but a sequence model like the CRF is really essential for strong performance on NER. Familiarity with CRF’s is assumed.
