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. Webb2 jan. 2024 · Additive. Based on above calculation, the profit allocation based on Shapley Values is Allan $42.5, Bob $52.5 and Cindy $65, note the sum of three employee’s Shapley values is 42.5+52.5+65 = 160.This actually proves Shapley Value’s additive property, all the attribute(or player)’s Shapley values must added to the total gain.. Now after explain …
Machine learning model explainability through Shapley values
Webb31 okt. 2024 · The most important feature by far here is application_type – but we see that it is actually pushing the model prediction away from the true label. Why would this happen? We can plot the distribution of application_type, split by the true label.We see that the application type is highly imbalanced, and only a small number of applications are … WebbCopy Command. Train a classification model and create a shapley object. When you create a shapley object, specify a query point so that the software computes the Shapley values for the query point. Then create a bar graph of the Shapley values by using the object function plot. Load the CreditRating_Historical data set. mini cooper awd hybrid
