Is anyone able to recommend some resources (preferably books) on the topic of neural networks that goes beyond that of introductory reading?
I'm still relatively new to the subject, however, I have successfully created my own neural network, so I wouldn't consider myself a beginner, so I'm looking for something more intermediate.
Neural Network Design (2nd edition) by Hagan et al. is one resource you could look at. It's a huge tome, weighing in at over 1000 pages in pdf form, but it is freely available (you can also buy a dead-tree version if you really want one).
Another good (although a bit old) and freely available online book (apart from the one suggested in this answer) is Neural Networks - A Systematic Introduction (1996) by Raul Rojas. This book contains several exercises at the end of each chapter and covers topics that you will not find in many online courses.
