Prophecy Distillation for Boosting Abstractive Summarization (2024.lrec-main)
Copied to clipboard
| Challenge: | Abstractive summarization models with maximum likelihood estimation generate unfaithful facts alongside ambiguous focus. |
| Approach: | They propose a framework which learns a regular summarization model to mimic the behavior of being guided by prophecy for boosting abstractive summaries. |
| Outcome: | The proposed model achieves new or matched state-of-the-art on four well-known datasets. |
Alleviating Exposure Bias in Abstractive Summarization via Sequentially Generating and Revising (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing approaches to abstractive summarization suffer from exposure bias . Existing solutions bridge this gap through un- or semi-supervised holistic learning . |
| Approach: | They propose to reformat abstractive summarization to sequential generation and revision (SeGRe) this allows the model to assess the flawed summary from a global perspective and modify inappropriate expressions. |
| Outcome: | The proposed model can assess the flawed summary from a global view and modify inappropriate expressions. |
Pre-train and Plug-in: Flexible Conditional Text Generation with Variational Auto-Encoders (2020.acl-main)
Copied to clipboard
| Challenge: | Existing conditional generation models cannot handle emerging conditions due to their joint end-to-end learning fashion. |
| Approach: | They propose a framework for conditional text generation that decouples the text generation module from the condition representation module to allow "one-to-many" conditional generation. |
| Outcome: | The proposed framework decouples the text generation module from the condition representation module to allow “one-to-many” conditional generation. |
