Internalizing LLM Reasoning via Discovery and Replay of Latent Actions

Zhenning Shi, Yijia Zhu, Junhan Shi, Xun Zhang, Lei Wang, Congcong Miao

Builds a library of activation edits from successful and failed reasoning traces, then selects edits during generation. Uses short lookahead checks to steer ongoing written reasoning, rather than replacing the trace with a sequence of hidden-state steps.
