In plain words: A generator stores past experience and produces batches of old situations to practice on, keeping old skills as the agent learns new ones. Results show these memories must be kept apart in the generator's space, without task labels, to avoid wiping out old skills.

Abstract

Our research is focused on understanding and applying biological memory transfers to new AI systems that can fundamentally improve their performance, throughout their fielded lifetime experience. We leverage current understanding of biological memory transfer to arrive at AI algorithms for memory consolidation and replay. In this paper, we propose the use of generative memory that can be recalled in batch samples to train a multi-task agent in a pseudo-rehearsal manner. We show results motivating the need for task-agnostic separation of latent space for the generative memory to address issues of catastrophic forgetting in lifelong learning.
