SharpSeq: Empowering Continual Event Detection through Sharpness-Aware Sequential-task Learning (2024.naacl-long)
Copied to clipboard
| Challenge: | Existing methods for continual event detection suffer from catastrophic forgetting . a novel continual learning paradigm leveraging sharpness-aware minimization is needed . |
| Approach: | They propose a continual learning paradigm that leverages sharpness-aware minimization and a generative model to balance training data distribution. |
| Outcome: | The proposed approach outperforms existing methods on real-world datasets. |
Lifelong Event Detection via Optimal Transport (2024.emnlp-main)
Copied to clipboard
| Challenge: | Continual event detection (CED) is a challenging task due to catastrophic forgetting, where learning new tasks hampers performance on previous ones. |
| Approach: | They propose a method that leverages optimal transport principles to align the optimization of a classification module with the intrinsic nature of each class, as defined by their pre-trained language modeling. |
| Outcome: | The proposed method outperforms state-of-the-art methods on MAVEN and ACE datasets and is a pioneering solution in continual event detection. |
