WebMay 12, 2024 · If we decide to build a number of binary classifiers, we need to interpret each model prediction. For instance, if we want to recognize four objects, each model tells you if the input data is a member of that category. Hence, each model provides a probability of membership. Similarly, we can build a final ensemble model combining those … WebApr 19, 2024 · At the bare minimum, the ROC curve of a model has to be above the black dotted line (which shows the model at least performs better than a random guess). Secondly, the performance of the model is measured by 2 parameters: True Positive (TP) rate: a.k.a. recall False Positive (FP) rate: a.k.a. probability of a false alarm
