flan-t5-small-stacked-samsum-1024

This model is a fine-tuned version of google/flan-t5-small on the stacked-summaries/stacked-samsum-1024 dataset. It achieves the following results on the evaluation set:

• Loss: 1.7573
• Rouge1: 46.6072
• Rouge2: 19.9754
• Rougel: 35.2715
• Rougelsum: 43.3599
• Gen Len: 72.64

Model Description

Trained on a summarization task with potentially multiple doc-summary pairs stacked on top of each other.

You can separate its predictions by using it's special token [NEXT_CONCEPT] to split the output into "separate topics".

Intended use & limitations

• This is intended to be used as a baseline/reference for comparison with the larger models.
