Researchers have introduced SCALE (Selective Control of Adaptation via Local Entropy), a novel method for supervised fine-tuning (SFT) that aims to improve model adaptation by controlling how learned features are used. Unlike existing methods that focus on suppressing or amplifying updates, SCALE freezes the pretrained model and the SFT delta, learning gates that suppress, reverse, or extrapolate features based on entropy reduction. This approach demonstrated superior performance in mathematical reasoning and code generation across several Qwen models, including Qwen2.5-Math-1.5B, Qwen2.5-Math-7B, and Qwen3-4B-Base, outperforming strong baselines while maintaining general retention.
