A new research paper published on arXiv introduces a theoretical framework for learning distributions from multiple, potentially overlapping data providers. The study focuses on a stylized model where a learner aims to reconstruct an unknown distribution by querying specific sets of data. The paper establishes that the learnability and sample complexity are directly influenced by the co-occurrence graph of these queryable sets, with a connected graph being necessary for consistency and a complete graph for PAC learning. The research also details optimal sample complexities ranging from nearly linear to quadratic, depending on the structure of the query family. AI
