Papers with redundancy problem
I already said that! Degenerating redundant questions in open-domain dialogue systems. (2023.acl-srw)
Copied to clipboard
| Challenge: | Neural text generation models have been successful in short open-domain conversations, but their performance degrades significantly in the long term. |
| Approach: | They propose a method to generate training data without crowdsourcing . they adapt negative training, decoding, and classification methods to mitigate redundancy problem . |
| Outcome: | The proposed method reduces the rate of redundant questions from 27.2% to 8.7% while improving the quality of the original model. |
Capturing Global Structural Information in Long Document Question Answering with Compressive Graph Selector Network (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to answer long document questions ignore the global structure of the long document, which is essential for long-range understanding. |
| Approach: | They propose a Compressive Graph Selector Network to capture the global structure of the long document in a compressive and iterative manner. |
| Outcome: | The proposed model outperforms existing methods on two datasets. |
3R: Enhancing Sentence Representation Learning via Redundant Representation Reduction (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to improve sentence representations lack fine-grained guidance on reducing redundant information. |
| Approach: | They propose a method that dynamically identifies redundant information from a dimensional perspective and trains the SRL model to redistribute semantics on different dimensions. |
| Outcome: | The proposed method improves sentence representations on seven semantic text similarity benchmarks. |
