# Samsum Pegasus (Reddit/TIFU) for conversational summaries

## Model description

Pegasus (Reddit/TIFU) for conversational summaries trained on the samsum dataset!

## Training data

The data is the [samsum](https://huggingface.co/datasets/samsum) dataset for conversional summaries.

The initial weigths were from the [google/pegasus-reddit_tifu](https://huggingface.co/google/pegasus-reddit_tifu). The hypothesis being that it would help the convergence on the samsum dataset to have weights trained on a larger summarization dataset first like the Reddit TIFU using casual language.

## Training procedure

Used the example/seq2seq/run_summarization.py script from the transformers source 4.5.0dev0.

  n_epochs: 3,\
  batch_size: 4, \
  max_source_length: 512,\
  max_target_length: 128

  Alexis: Thanks Carter, I'm flattered. But I have a really busy week coming up.\\r\
  Carter: Yeah, no worries. I totally understand. But if you ever want to go grab dinner again, just let me know.\\r\
