Universal Activation Verbalizer: A Unified Framework for Cross-Model Activation Explanation 事件

Universal Activation Verbalizer: A Unified Framework for Cross-Model Activation Explanation arXiv:2605.25903v1 Announce Type: new Abstract: Activation verbalization explains hidden representations in natural language, but existing methods are mostly limited to self-explanation, where each model explains only its own activations. We introduce Universal Activation Verbalizer (UAV), a framework that uses a shared decoder to explain activations from heterogeneous donor models. UAV learns a lightwei
