pegasus-large-reddit_tifu-samsum-256

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 dataset for conversional summaries.

The initial weigths were from the 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

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.
