Shapely Values

1. The Shapley value is a solution concept used in game theory that involves fairly distributing both gains and costs to several actors working in coalition. Game theory is when two or more players or factors are involved in a strategy to achieve a desired outcome or payoff. The Shapley value applies primarily in situations when the contributions of each actor are unequal, but each player works in cooperation with each other to obtain the gain or payoff. Shapley value is a concept in game theory used to determine contribution of each player in a coalition or a cooperative game. In machine learning - for prescriptive analytics shapely values are used to find contribution from each of the features to outcome Very good video on the explanation of what a shap value is: https://www.youtube.com/watch?v=-taOhqkiuIo https://www.youtube.com/watch?v=9haIOplEIGM&t=184s https://www.youtube.com/watch?v=VB9uV-x0gtg https://www.youtube.com/watch?v=VB9uV-x0gtg
