Towards a General Framework for Continual Learning with Pre-training

1 code implementation21 Oct 2023 Liyuan Wang, Jingyi Xie, Xingxing Zhang, Hang Su, Jun Zhu

In this work, we present a general framework for continual learning of sequentially arrived tasks with the use of pre-training, which has emerged as a promising direction for artificial intelligence systems to accommodate real-world dynamics.

Hierarchical Decomposition of Prompt-Based Continual Learning: Rethinking Obscured Sub-optimality

1 code implementation NeurIPS 2023 Liyuan Wang, Jingyi Xie, Xingxing Zhang, Mingyi Huang, Hang Su, Jun Zhu

Following these empirical and theoretical insights, we propose Hierarchical Decomposition (HiDe-)Prompt, an innovative approach that explicitly optimizes the hierarchical components with an ensemble of task-specific prompts and statistics of both uninstructed and instructed representations, further with the coordination of a contrastive regularization strategy.

SegFix: Model-Agnostic Boundary Refinement for Segmentation

4 code implementations ECCV 2020 Yuhui Yuan, Jingyi Xie, Xilin Chen, Jingdong Wang

We present a model-agnostic post-processing scheme to improve the boundary quality for the segmentation result that is generated by any existing segmentation model.
