SpletIf the ROC curve to smooth was generated with an ordered factor only binormal smoothing can be applied and the message “ROC curves of ordered predictors can be smoothed … SVC is a similar method that also builds on kernel functions but is appropriate for unsupervised learning. Multiclass SVM aims to assign labels to instances by using support vector machines, where the labels are drawn from a finite set of several elements. The dominant approach for doing so is to reduce the single multiclass problem into …

SpletIf you want to get around the problem of picking the 'best' threshold, you can use 11-pt Mean Average Precision. This measures the AP for threshold values [0.0, 0.1, 0.2, ..., 1.0] (thus the 11 pt). Share Cite Improve this answer Follow answered Jul 7, 2011 at 18:24 user5268 104 3 Add a comment 1
