This repository provides implementations of core NLP tasks including word embeddings (Word2Vec, GloVe), various text classification models (TextCNN, FastText, TextRCNN, BERT variants), named entity recognition approaches (BERT-CRF, BERT-MRC), text summarization methods (seq2seq, Transformer, GPT), sentence similarity computation, multi-label classification, and relation extraction. All implementations use PyTorch and the Hugging Face Transformers library for pretrained models.
