Confidence value of the multiclass SVM
Hi, As suggested link text. I am using superpixels. I have trained the multi class SVM by using INTER kernel. I want to find out confidence value. How shall I get the confidence value of predicated superpixels.
Thanks
opencv's SVM can't really give you confidence values for classification.
you can try to set the RAW_OUTPUT flag in the predict method, to get the "distance to the margin" , but that would only make sense in a 2-class case, not for multiple.
