how to train and predict from multiple xml files?

I created 2 xml(positive and negative) files for a sign board(100 speed). The positive files are the HOG descriptor values of one sign(100 speed) and negative files(80 speed and stop sign) the HOG descriptor values of other two signs. Now i want to train the ANN using these 2 files to detect 100 speed sign board. How should i train for all 3 signs and predict the sign for any of the given sign?

can you show some example images from your trainset ?

So you have a single positive instance and 2 negative instances? Then I am afraid, ANN is never going to converge to a solution... or do you have multiple descriptors for each class?
