WebMar 1, 2024 · This shortcoming renders it impossible to ascertain if a given feature can yield divergent effects depending on the sample being evaluated, as shown by the SHAP values presented in Figure 9. Consequently, the feature importance derived from LightGBM is usually deemed unsatisfactory for explaining models due to its lack of granularity. WebFairGBM. FairGBM is an easy-to-use and lightweight fairness-aware ML algorithm with state-of-the-art performance on tabular datasets. FairGBM builds upon the popular LightGBM algorithm and adds customizable constraints for group-wise fairness (e.g., equal opportunity, predictive equality) and other global goals (e.g., specific Recall or FPR …

WebMonotonic constraint to enforce on each feature are specified using the following integer values: 1: monotonic increase 0: no constraint -1: monotonic decrease If a dict with str keys, map feature to monotonic constraints by name. If an array, the features are mapped to constraints by position. WebSep 16, 2024 · In the following example, let’s train too models using LightGBM on a toy dataset where we know the relationship between X and Y to be monotonic (but noisy) and … WebRegression LightGBM Learner. Gradient boosting algorithm. Calls lightgbm::lightgbm () from lightgbm . The list of parameters can be found here and in the documentation of lightgbm::lgb.train () . Note that lightgbm models have to be saved using lightgbm::lgb.save, so you cannot simpliy save the learner using saveRDS. lightyear one car stock
