The Sample Complexity of Multiclass and Sparse Contextual Bandits

Researchers present optimal algorithms for sparse contextual bandits that achieve sample complexity of Õ((s/ε² + |A|/ε)log|Π|/δ), closing a gap from prior work that had exponential dependence on action set size. The results apply to multiclass classification and combinatorial semi-bandits through information-theoretic and algorithmic approaches.

MIFair: A Mutual-Information Framework for Intersectionality and Multiclass Fairness

Researchers introduce MIFair, a machine learning framework using mutual information to assess and mitigate bias in AI systems, with particular strength in handling intersectionality and multiclass classification. The framework consolidates diverse fairness metrics into a unified approach and demonstrates effectiveness on real-world datasets while maintaining predictive performance.
