Researchers have developed new methods for approximating Shapley values, a crucial metric for attribution in machine learning. Two papers introduce novel algorithms, Adalina and ShaplEIG, that improve efficiency and accuracy in estimating these values, particularly for large numbers of "players" or features. Another paper, OddSHAP, provides a theoretical justification for paired sampling techniques and introduces a new estimator that leverages this insight to achieve state-of-the-art accuracy. AI
