Webb14 juli 2024 · The plot will allow you to decide on a value that satisfies your requirements (i.e. how much will your precision suffer when you want 95% recall). You can select it based on your desired value in one metric (e.g. 95% recall), but really I'd just plot it and have a look. You can do it in SKLearn with plot_roc_curve. Share.

Cutoff Rate and Probability Table. DM algorithms classify via a two-step process. First, the algorithm estimates the probability of belonging to the class of interest. Next, it compares that computed probability to the cutoff value, and classifies the instance accordingly. If the probability meets or exceeds the cutoff value, it assigns it ...
WebbI reset the probabilistic cutoff to a much lower value rather than the default 0.5 according to the ROC curve. Then I can improve the sensitivity (recall) but meanwhile sacrificed the precision. Just wanna confirm that the default 0.5 is not much meaningful and a practical probabilistic cutoff was often derived from ROC curve in practice. WebbManager, Enterprise Sales Development.
