Shap binary classification
Webbof Shap computation is provably hard, actually #P-hard for several kinds of binary classification models, indepen-dently from whether the internal components of the model are used when computing Shap (Bertossi et al. 2024; Arenas et al. 2024a; Arenas et al. 2024b). However, there are classes of classifiers for which, using the model components WebbI was wondering if it’s a way SHAP handles missing values that’s different from XGboost? Any insights/discussion regarding missing values here would be highly appreciated. EDIT: For context, the model is a binary classification model but with heavy imbalance (so I ended up optimizing for F1/F2 metric and applied cost sensitive learning).

WebbTree SHAP ( arXiv paper) allows for the exact computation of SHAP values for tree ensemble methods, and has been integrated directly into the C++ LightGBM code base. This allows fast exact computation of SHAP values without sampling and without providing a background dataset (since the background is inferred from the coverage of the trees).

Webb1 nov. 2024 · SHAP deconstructs a prediction into a sum of contributions from each of the model's input variables. [ 1, 2] For each instance in the data (i.e. row), the contribution from each input variable (aka "feature") towards the model's prediction will vary depending on the values of the variables for that particular instance.
