WebbSHAP Values Review ¶. Shap values show how much a given feature changed our prediction (compared to if we made that prediction at some baseline value of that feature). For example, consider an ultra-simple model: y = 4 ∗ x 1 + 2 ∗ x 2. If x 1 takes the value 2, instead of a baseline value of 0, then our SHAP value for x 1 would be 8 (from ... WebbBNPy (or bnpy) is Bayesian Nonparametric clustering for Python. Our goal is to make it easy for Python programmers to train state-of-the-art clustering models on large datasets. We focus on nonparametric models based on the Dirichlet process, especially extensions that handle hierarchical and sequential datasets. read em and weep 意味
