Episodic looking - using reinforcement learning to bias perception enhances few-shot and continual learning with protection from forgetting

Read the original on arXiv AI →

The paper addresses the conflict between generalization and continuous adaptation in few‑shot and continual learning. It proposes a Complementary Learning System (CLS) that separates a fast Short‑Term Memory (STM) for memorizing recent inputs from a slow Long‑Term Memory (LTM) that provides robust, generalized perceptions. Experiments on image classification show the CLS model resists forgetting in domain‑incremental continual learning and outperforms other continual learners in few‑shot settings, though overall accuracy is slightly lower than some existing methods.

Drift-adaptive Representation Preservation for Domain-Incremental Learning

The paper proposes a drift‑adaptive method for Domain‑Incremental Learning that tracks representation drift for each past domain‑class pair. By measuring how much a concept’s current representation deviates from a fixed anchor, the method assigns stronger preservation to high‑drift pairs and down‑weights highly drifted domains during prototype construction. Experiments on DomainNet, Office‑Home, CORe50, and CDDB‑Hard show that this approach maintains a strong accuracy‑forgetting balance while using less training memory and the smallest storage compared to other methods.

Trust Region Continual Learning as an Implicit Meta-Learner

The paper introduces Trust Region Continual Learning, a hybrid approach that blends generative replay with a Fisher-metric trust region constraint to address catastrophic forgetting in sequential task learning. It demonstrates that, under local approximations, the update can be interpreted as a single-step Model-Agnostic Meta-Learning (MAML) process, where replay provides an old-task gradient and the Fisher penalty shapes curvature. Experiments on task-incremental diffusion image generation and continual diffusion-policy control show that this method achieves superior final performance, better retention, and faster early-task recovery compared to EWC, replay, and other continual meta-learning baselines.
