Class-Incremental Learning based on Label Generation
Yijia Shao, Yiduo Guo, Dongyan Zhao, Bing Liu · 2023
Despite the great success of pre-trained language models, it is still a challenge to use these models for continual learning, especially for the class-incremental learning (CIL) setting due to catastrophic forgetting (CF).This paper reports our finding that if we formulate CIL as a continual label generation problem, CF is drastically reduced and the generalizable representations of pre-trained models can be better retained.We thus propose a new CIL method (VAG) that also leverages the sparsity of vocabulary to focus the generation and creates pseudo-replay samples by using label semantics.Experimental results show that VAG outperforms baselines by a large margin. 1
