I went through multiple resources on the net until it clicked for me. I guess each book / video / blog post gives you the bits you are ready for, and when enough of these bits accumulate you understand it. Looking back, neural networks are not that difficult to grasp, but there are many important details that one should understand. What I learned is that it is very important to test intermediate results thoroughly. Nets will gladly learn from garbage if that is what you (unknowingly) feed them, and they might even produce some results - not at acceptable level though. I didn't continue working in this field, but I'm happy I learned it (and used it in a project too) and would recommend that to any developer. ML really moves the frontier of what we can achieve in software much further.
