WebFeb 23, 2024 · However, my auc is 80% which feels like a decent figure to look at. Now my question is as follows. a) Irrespective of business decision to keep/reject the model, based on the above metrics alone, how do I know my model is performing? I read that AUC talks about discriminative ability between the positive and negative classes. WebJan 7, 2024 · We first have to remove the 3 new features from the test set and then evaluate the original model. The original random forest has already been trained on the original data and code below shows preparing the testing features and evaluating the performance (refer to the notebook for the model training). # Find the original feature indices WebNov 12, 2024 · The AUC curve can be computed using Wilcoxon-Mann-Whitney statistic: If x and y are probabilities, the metric penalizes any occurrence where the probability of the … rachel miriam smerd
