# BART_corrector

This model is a fine-tuned version of [ainize/bart-base-cnn](https://huggingface.co/ainize/bart-base-cnn) on a homemade dataset. Each sample of the dataset is an english sentence that has been duplicated 10 times and where random errors (7%) were added.

It achieves the following results on the evaluation set:
- Loss: 0.0025
- Rouge1: 81.4214
- Rouge2: 80.2027
- Rougel: 81.4202
- Rougelsum: 81.4241
- Gen Len: 19.3962
