Thanks for your nice works!If I want to use another datasets from "mulan",such as emotion ,how can i convert it to datasets paper used ?I saw the words in the top of the preprocess.py "../data/reuters/train_inputs.txt -train_tgt ../data/reuters/train_labels.txt”, but i don't know the detail of the train_inputs.txt or train_labels.txt.Can you give an example of such type.Thank!
