Introduction of pegasus-large-summary-explain

Model Details of pegasus-large-summary-explain

pszemraj/pegasus-large-summary-explain

This model is a fine-tuned version of google/pegasus-large on the booksum dataset for four total epochs.

It achieves the following results on the evaluation set:

  • eval_loss: 1.1193
  • eval_runtime: 6.6754
  • eval_samples_per_second: 27.714
  • eval_steps_per_second: 1.798
  • epoch: 3.0
  • step: 900

A 1-epoch checkpoint can be found at pszemraj/pegasus-large-book-summary , which is where the second training session started from.

Model description
  • After some initial tests, it was found that models trained on the booksum dataset seem to inherit the summaries' SparkNotes-style explanations; so the user gets a shorter and easier-to-understand version of the text instead of just more compact.
  • This quality (anecdotally) is favourable for learning/comprehension because summarization datasets that simply make the information more compact (* cough * arXiv) can be so dense that the overall time spent trying to comprehend what it is saying can be the same as just reading the original material.
Intended uses & limitations
  • standard pegasus has a max input length of 1024 tokens, therefore the model only saw the first 1024 tokens of a chapter when training, and learned to try to make the chapter's summary from that. Keep this in mind when using this model, as information at the end of a text sequence longer than 1024 tokens may be excluded from the final summary/the model will be biased towards information presented first.
