Revision history [back]

I have trained my character's classifier using Opencv's Support Vector Machine. But the outcome is not good as expected. My classifier always classify wrongly even for the training data.

The sample size I used in class 0-9 for each is about 15000, while the sample size of class A-Z for each is about 1500 - 4000. Now I want to try to use some of deep learning libraries, but I don't know whether it is practical to change. I have looked into Caffe and Eblearn, but they may not be suitable to integrate to my development platform Vs2005. Could anyone give some suggestions to me?
