In this vignette we compare fastshap with the shap Python module. In particular, we’ll compare fastshap::explain () with the shap.SamplingExplainer () method which provides the same Monte Carlo approach to computing ApproxSHAP (ApproxSHAP) values described in Štrumbelj and Kononenko (2014); in particular, see Algorithm 1.
