Overview

This model is a fine-tuned version of allenai/led-base-16384 on the MS^2 dataset. The model received as input the background section and 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 MS2 leaderboard for results on the blind test set.

It achieves the following results on the evaluation set:

• Loss: 3.7602
• Rouge1 Fmeasure Mean: 28.5338
• Rouge2 Fmeasure Mean: 9.5060
• RougeL Fmeasure Mean: 20.9321
• RougeLsum Fmeasure Mean: 24.0998
• Bertscore Hashcode: microsoft/deberta-xlarge-mnli_L40_no-idf_version=0.3.11(hug_trans=4.21.0.dev0)-rescaled_fast-tokenizer
• Bertscore F1 Mean: 22.7619
• Seed: 42
• Model Name Or Path: allenai/led-base-16384
• Doc Sep Token: "</s>"
