    Classification Accuracy is Not Enough: More Performance

    Mar 20, 2014 When training a classifier (e.g. DNN based) with a continuous output p is it possible to specifically optimize for e.g. high recall? I am not talking about just making a cut on p at a point where recall is high but for instance setting a high recall goal e.g. 95% and minimizing the false positive rate obtainable at that recall goal

    Conversely, if you have a classifier that predicts y equals zero, almost all the time, that is that it predicts y=1 very sparingly, this corresponds to setting a very high threshold using the notation of the previous y. Then you can actually end up with a very high precision with a very low recall

    Nov 25, 2014 A single threshold can be selected and the classifiers’ performance at that point compared, or the overall performance can be compared by considering the AUC. Most published reports compare AUCs in absolute terms: “Classifier 1 has an AUC of 0.85, and classifier 2 has an AUC of 0.79, so classifier 1 is clearly better“. It is, however, possible to calculate whether differences in AUC
