Here’s a list of books I’ve read that I would recommend. I’ve tried to put them into categories, but some could fit in more than one. Check out my resume to have a better idea of where I’m coming from because programmers with different backgrounds might prefer different books even if most of the books I recommend here are “classics”.
While buying these books directly from my site would sponsor me (I’ve added references to each of these links), I recommend that you check on Pricenoia if you could order them for less from another Amazon site.
A quick note concerning Neural Network Design, I ordered it directly from the University of Colorado.
