# 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: 8, \
  max_source_length: 256,\
  max_target_length: 128

    from transformers import PegasusForConditionalGeneration, PegasusTokenizer
    
    model_name = "jpcorb20/pegasus-large-reddit_tifu-samsum-256"
    
    tokenizer = PegasusTokenizer.from_pretrained(model_name)
    model = PegasusForConditionalGeneration.from_pretrained(model_name)

Yeah, I really enjoyed myself as well.\r\nCarter: If you are up for it, I would really like to see you again soon.\r\nAlexis: Thanks Carter, I'm flattered. But I have a really busy week coming up.\r\nCarter: Yeah, no worries. I totally understand. But if you ever want to go grab dinner again, just let me know.\r\nAlexis: Yeah of course. Thanks again for tonight. Carter: Sure. Have a great night.\r\n"""
