Class probability score翻译

WebMay 23, 2024 · A probability can be used as a score (even in the multiclass case). Many Scikit-learn models, such as Tree-based methods, ensemble methods, kNN, and Naive Bayes have a predict_proba method; but these should really be thought of as giving scores rather than "true" probabilities. WebMar 15, 2024 · In-order to address these i set scikit-learn Random forest class_weight = 'balanced', which gave me an ROC-AUC score of 0.904 and the recall for class- 1 was 0.86, now when i tried to further improve the AUC Score by assigning weight, there wasn't any major difference with the results, i.e Class_weight = {0: 0.5, 1: 2.75}, assuming this …
