WebApr 10, 2024 · scikit-learn's contrib package, imbalanced-learn, has a function, geometric_mean_score(), which has the following in its documentation:. The geometric mean (G-mean) is the root of the product of class-wise sensitivity. This measure tries to maximize the accuracy on each of the classes while keeping these accuracies balanced. WebThe classes in the sklearn.feature_selection module can be used for feature selection/dimensionality reduction on sample sets, either to improve estimators’ accuracy …

WebJan 24, 2024 · The precision_recall_curve and roc_curve are useful tools to visualize the sensitivity-specificty tradeoff in the classifier. They help inform a data scientist where to set the decision threshold of the model to maximize either sensitivity or specificity. This is called the “operating point” of the model.
