Bilstm-crf loss
WebJan 3, 2024 · QUOTE: This repository contains a BiLSTM-CRF implementation that used for NLP Sequence Tagging (for example POS-tagging, Chunking, or Named Entity Recognition ). The implementation is based on Keras 2.1.5 and can be run with Tensorflow 1.7.0 as backend. It was optimized for Python 3.5 / 3.6. It does not work with Python 2.7. WebMeanwhile, compared with BERT-BiLSTM-CRF, the loss curve of CGR-NER is lower and smoother, indicating the better fit of the CGR-NER model. Moreover, to demonstrate the computational cost of CGR-NER, we also report the total number of parameters and the average time per epoch during training for both BERT-BiLSTM-CRF and CGR-NER in …
