Shapley value

WebbAbstract. Shapley value is a popular approach for measuring the influence of individual features. While Shapley feature attribution is built upon desiderata from game theory, some of its constraints may be less natural in certain machine learning settings, leading to unintuitive model interpretation. In particular, the Shapley value uses the ... Webb우리는 shapley value를 사용하여 자궁경부암을 예측하는 랜덤 포레스트 모델의 예측을 분석합니다. 그림 5.46: 자궁경부암 데이터 세트에 있는 여성에 대한 shapley value. 0.57의 …
