Begin to deep learning

Ten years ago, everyone thought that Artifical neural network is obsoleted and here they are wrong.
Deep learning one of the biggest breakthrough in AI (not sure if in the AI history or not), but it successfully applied in several domains. Many researchers attempted to use deep learning technology to improve
their classification accuracies and mostly in image recognition, face detection, etc.

I have played around with Caffee and Theano lately. Still couldn’t decide which framework to use for my project.
