WebbShapley Documentation. Shapley is a Python library for evaluating binary classifiers in a machine learning ensemble. The library consists of various methods to compute (approximate) the Shapley value of players (models) in weighted voting games (ensemble games) - a class of transferable utility cooperative games. WebbLloyd Shapley in 2012. The Shapley value is a solution concept in cooperative game theory. It was named in honor of Lloyd Shapley, who introduced it in 1951 and won the Nobel Memorial Prize in Economic Sciences for it in 2012. [1] [2] To each cooperative game it assigns a unique distribution (among the players) of a total surplus generated by ...
