Hi Albert, Thank you for replying. You are right, a high FPR might indicate an overfitting problem. I have been having discussions with friends and our insight so far is that I was worrying a non-existent problem. Feeding two dataset of both 'Normal Classes' into the 'decision_function' of OCSVM

Hi Ady, Overfitting is a possible explanation. If your model learnt your normal scenarios too well then every abnormal data will be predicted as abnormal (so you will have a good performance for anomalies) however none of the normal instances of the test set will be in the normal region (so you w
