Dataset Card
This is a dataset containing ML ArXiv papers. The dataset is a version of the original one from CShorten, which is a part of the ArXiv papers dataset from Kaggle. Three steps are made to process the source data:
- useless columns removal;
- train-test split;
- '\n' removal and trimming spaces on sides of the text.
