> "A Deep Learning system does not have a temporal component" but isnt that what recursive deep learning is for. Yes, recurrent nets exist, and have since the 80s, before even convolutional nets. The authors seem a bit out of the loop, considering the (more recent) success of RNNs in speech recognition... Arguably this article itself describes a type of RNN.
