A new research paper published on arXiv details the sample complexity of multicalibration for multilevel properties. The study establishes matching upper and lower sample-complexity bounds for sequences of k properties, demonstrating that achieving a certain error rate requires a number of samples that grows with the complexity of the properties. The findings are instantiated for three canonical examples and have implications for understanding the data requirements of sophisticated prediction tasks. AI
