Little by Little: Continual Learning via Incremental Mixture of Rank-1 Associative Memory Experts
arXiv:2506.21035v5 Announce Type: replace Abstract: Continual learning (CL) with large pre-trained models aims to incrementally acquire knowledge without catastrophic forgetting. Existing LoRA-based Mixture-of-Experts (MoE) methods expand capacity by adding isolated new experts while freezing old ones, but still suffer from redundancy, interference, routing ambiguity, and consequent forgetting. We investigate the issues stemming from coarse-grained expert granularity. Coarse-grained experts (e.g., high-rank LoRA) encode low-specialty information, leading to expert duplication/interference and
The rapid advancement of large pre-trained AI models necessitates more efficient and robust continual learning methods to scale their capabilities without memory and processing bottlenecks.
Improving continual learning directly impacts the long-term viability and efficiency of AI systems, reducing 'catastrophic forgetting' and enabling more adaptable, powerful models crucial for various applications.
This research proposes a method to optimize continual learning in large AI models by addressing expert redundancy and interference, potentially leading to more scalable and flexible AI development.

More efficient and adaptable AI models are developed, reducing the computational burden of continual learning.
This efficiency could accelerate the deployment of complex AI agents and autonomous systems requiring continuous knowledge updates.
Reduced compute needs for continual learning might slightly ease pressure on compute supply chains, or at least shift focus towards other bottlenecks.
