WebOct 22, 2024 · Description Compute fast (approximate) Shapley values for a set of features using the Monte Carlo algorithm described in Strumbelj and Igor (2014). An efficient algorithm for tree-based models, commonly referred to as Tree SHAP, is also supported for lightgbm and xgboost models; see Lundberg et. al. (2024) for details. Usage explain … WebIf you have the appropriate dependencies installed (i.e., reticulate and shap) then you can utilize shap ’s additive force layout (Lundberg et al. 2024) to visualize fastshap ’s prediction explanations; see ?fastshap::force_plot for details. # Visualize first explanation force_plot (object = ex [1L, ], feature_values = X [1L, ], display = "html")

WebThe main selling point of fastshap is speed! For example, all three packages (in fact, all general and practical implementations of Shapley values) use in approximation algorithm that often requires a large number of Monte Carlo repetitions to achieve accurate results.
