arXiv:2606.00382v1 Announce Type: new Abstract: Sequential fine-tuning of large language models forces a choice: let the shared substrate keep learning and accept catastrophic forgetting, or freeze it after task one and foreclose cross-task refinement. Per-task adapter methods (LoRAHub, AdapterFusion, PackNet, Progressive Networks) take the second path. We introduce CRMA (Constrained Residual Mixing Adapter), a residual adapter whose internal mixing matrix M is doubly-stochastic at every forward pass via Sinkhorn normalization, so by Birkhoff's theorem ||M||_2 <= 1 holds by construction -- a s
This research addresses a core challenge in LLM development—balancing continuous learning with catastrophic forgetting—which is critical for the next generation of AI systems that need to adapt and evolve.
It introduces a novel architectural approach that could significantly improve the efficiency and adaptability of large language models, enabling them to learn new tasks without compromising prior knowledge.
The ability to fine-tune LLMs continually and modularly without catastrophic forgetting could lead to more robust, efficient, and versatile AI systems, reducing the need for complete retraining.
