As said in a respected blog, "Maybe it’s too early to call, but [...] it looks like Neural Networks are making a comeback." Some of the networks that are currently developed are Autoencoders and Convolution Networks. Where could one find some tutorials/articles on these topics?
Andrew Ng's cs294a course at Stanford Deep Learning and Unsupervised Feature Learning has some nice freebies on sparse autoencoders:
