Two new arXiv papers explore theoretical frameworks for sequential decision-making in machine learning. The first paper introduces a "mechanistic information" metric to quantify the value of hybrid models that combine physical priors with learned residuals, demonstrating sample-efficiency gains in simulations and cautioning against LLM priors in safety-critical applications. The second paper develops a sequential supersample framework to establish information-theoretic generalization bounds for adaptive data settings, applicable to online learning, streaming active learning, and bandits.
