New theory defines support sufficiency for robust decision-making

This paper introduces a new formulation for robust decision-making, defining "support sufficiency" as action-sufficient compression. It proposes that a system must retain only the distinctions necessary to act appropriately given the current payoff structure. The research formalizes this concept by distinguishing between exact and approximate sufficiency, with the latter defined by bounded expected policy regret. The work suggests that effective decision-making requires preserving distinctions relevant to actions, rather than all support information or reconstruction fidelity. AI
