A new paper introduces the concept of a "structure gap" in AI, arguing that for certain problems, explicit domain knowledge is more crucial than simply increasing data volume. The research defines structure-encoded problems where known structures like graphs or physical laws significantly constrain the input-output mapping. The paper demonstrates that methods leveraging this structure can achieve optimal performance, while purely data-driven learners may face persistent uncertainty and excess risk, even with vast datasets. Experiments in areas like sparse recovery and graph reachability illustrate how incorporating validated structure can refine hypothesis spaces and improve learning outcomes. AI
