Webb11 dec. 2024 · 1 Answer. You should pass the prediction probabilities to roc_auc_score, and not the predicted classes. Like this: When you pass the predicted classes, this is actually the curve for which AUC is being calculated (which is wrong): from sklearn.metrics import roc_curve, auc fpr, tpr, _ = roc_curve (y_test, yPred) roc_auc = auc (fpr, tpr) plt ...

Webb25 juni 2024 · 2. There are some concerns with your comparison, but rectifying them does not resolve the issue; so, this is only a partial answer. First, the MLP classifier includes a bias (intercept) node by default (the presence of which, unlike with LR, is not customizable), so you need fit_intercept = True in LR. Second, despite the same solvers in both ... Webb23 sep. 2024 · MLPclassifier又称多层感知机Multiple layers perception或神经网络,在sklearn库中的该分类器有以下参数: from sklearn.neural_network import … hdmioil
