Leveraging Non-dialogue Summaries for Dialogue Summarization

no code implementations TU (COLING) 2022 Seongmin Park, Dongchan Shin, Jihwa Lee

To mitigate the lack of diverse dialogue summarization datasets in academia, we present methods to utilize non-dialogue summarization data for enhancing dialogue summarization systems.

Finetuning Pretrained Transformers into Variational Autoencoders

1 code implementation EMNLP (insights) 2021 Seongmin Park, Jihwa Lee

Text variational autoencoders (VAEs) are notorious for posterior collapse, a phenomenon where the model's decoder learns to ignore signals from the encoder.
