Shapley value regression in r
Webb23 dec. 2024 · Two techniques are proposed: the orthonormal matrices used for the relative importance by Gibson and R. Johnson, and the cooperative game theory by Shapley value of predictors in regression. WebbMisha was a core member of the team. He brought many machine learning models to our team, including LightGBM, ExtraTrees, Random Forest, and SGD classifiers. It was clear when we teamed that Misha had spent a lot of time analyzing the dataset, cleaning it, and making better features from the raw values.

WebbShapley values have a fairly long history in the context of feature importance.Kruskal(1987) andLipovetsky & Con-klin(2001) proposed using the Shapley value to analyze global feature importance in linear regression by using the value function v f(S) to represent the R2 of a linear model f built on predictors S, to decompose the variance explained
WebbWe propose a novel definition of Shapley values with uncertain value functions based on first principles using probability theory. Such uncertain value functions can arise in the context of explainable machine learning as a result of non-deterministic algorithms. great detectives poirot and marpleWebbOnce we have these three components we can create a predictor object.
