WebJun 11, 2024 · I implemented a bidirectional Long Short-Term Memrory Neural Network with a Conditional Random Field Layer (BiLSTM-CRF) using keras & keras_contrib … WebAug 28, 2024 · For this reason, in this paper we propose a training approach for the BiLSTM-CRF that leverages a hinge loss bounding the CoNLL loss from above. In addition, we present a mixed hinge loss that bounds either the CoNLL loss or the Hamming loss based on the density of entity tokens in each sentence.
