Researchers have introduced Entropic Control for Homeostatic Optimization (ECHO), a new framework designed to combat catastrophic forgetting in large language models during supervised fine-tuning. ECHO utilizes output entropy as a real-time proxy to detect forgetting risks, bypassing the need for costly reference-model inferences. An elastic controller then dynamically adjusts the gradient weight of replay data based on deviations from a pre-trained entropic equilibrium. Evaluations on models ranging from 0.6B to 9B parameters show ECHO improves the plasticity-stability trade-off and maintains robustness across different data mixing ratios. AI
