Learning to Prompt for Continual Learning

The mainstream paradigm behind continual learning has been to adapt the model parameters to non-stationary data distributions, where catastrophic forgetting is the central challenge. Surprisingly, L2P achieves competitive results against rehearsal-based methods even without a re-hearsal buffer and is directly applicable to challenging task-agnostic continual learning.

• 1 Typical methods rely on a rehearsal buffer or known task identity at test time to retrieve learned knowl-edge and address forgetting, while this work presents a new paradigm for continual learning that aims to train a more succinct memory system without accessing task identity at test time.
• 2 Our method learns to dynamically prompt (L2P) a pre-trained model to learn tasks sequen-tially under different task transitions.
• 3 In our proposed framework, prompts are small learnable parameters, which are maintained in a memory space.

This research advances how AI systems learn, reason, and solve problems — with direct implications for automation and scientific discovery.
