Recommended papers for deep learning based classification?
Maybe reading papers is a bit hard, because they usually don't explain everything. I suggest you watching deep learning specialization by professor Andrew Ng, which is brief and easy to figure out. If you insist on reading papers, this three sequential articles may help you. Choosing neural networks highly depend on your task. For most computer vision tasks convolutional neural nets are used. You can also take a look at here which contains different resources and discussions and many other useful stuff.
