WebJan 28, 2024 · TreeSHAP is an algorithm to compute SHAP values for tree ensemble models such as decision trees, random forests, and gradient boosted trees in a polynomial-time proposed by Lundberg et. al (2024)¹. The algorithm allows us to reduce the complexity from O (TL2^M)to O (TLD^2) (T = number of trees in the model, L = maximum number of leaves … WebOct 5, 2024 · Therefore, it is important to consider model's output in order to interpret SHAP values correctly. Finally, when you calculate feature importance, you calculate the average contribution for all instances in dataset, so values are not summing to 1 necessarily, because you have negative and positive contributions, and your average output is not 1 … http://www.iotword.com/6061.html kerry clifford
