Less Is More in Federated Continual Learning: RieSelect for Conflict-Aware Layer Selection in LLMs

Federated continual learning (FCL) of large language models on edge devices is constrained by a communication--stability--plasticity trilemma. We reveal a less-is-more phenomenon: beyond a moderate layer upload ratio, stability loss offsets saturated plasticity gains, so overall continual performanc…
