This project includes all the variants of DATNet (i.e., base model, DATNet-F, DATNet-P) implementations reported in the paper.

• numpy 1.10+
• matplotlib 1.8+
• tensorflow 1.6+
• python 3.6
• scikit-learn 1.16+

To train a DATNet model, run:

$ python3 train_datnetf_model.py --task conll2003_ner \  # indicate the dataset for training
                        --use_gpu true \  # use GPU
                        --gpu_idx 0 \  # specify which GPU is utilized                    
                        ...
