Overview
This model is a fine-tuned version of allenai/led-base-16384 on the Cochrane dataset. The model received as input the titles and abstracts of up to 25 included studies for each example, concatenated by the "</s>" token. Global attention is applied to the special start token "<s>" and each of the document separator tokens "</s>". The model slightly outperforms the reported results in the original paper: MS2: Multi-Document Summarization of Medical Studies. See the Cochrane leaderboard for results on the blind test set.
It achieves the following results on the validation set:
- Loss: 4.0216
- Rouge1 Fmeasure Mean: 26.3026
- Rouge2 Fmeasure Mean: 6.0324
- Rougel Fmeasure Mean: 18.1513
- Rougelsum Fmeasure Mean: 22.5031
