DCGAN Paper

It's always good to take a look at the original paper when you can. Many papers discuss both the theory and training details of deep learning networks, and you can read the DCGAN paper, Unsupervised Representational Learning with Deep Convolutional Generative Adversarial Networks, at this link. I especially like the section they have on model architectures, which is pasted for convenience as an image, below.

Architecture guidelines for stable DCGANs.
