I am a php developer learning python for one reason, i wanna learn ai and i think that python would be better than php at that. I tried finding tutorials on how to build a neural network but they all use libraries. I am very interested in building the algorythm myself to understand how it actually works completly. I would use libraries once i have full understanding of how neural networks works. Sorry if this is too broad. But any explanation of neural networks or examples (without libraries) are much appreciated. Thanks

Neutral networks requires advanced mathematics to understand. If you don't mind the complexity, goto:


The section The code for backpropagation has what you want. The Github link is https://github.com/mnielsen/neural-networks-and-deep-learning

  • $\begingroup$ Thank you very much i just got home from work and i get to read avout something i love :) $\endgroup$ – red security Mar 28 '17 at 3:04
  • $\begingroup$ I just did, thanks :) the math is a little complicated but i will read chapter 1 first maybe i can get a better idea of what is going on $\endgroup$ – red security Mar 28 '17 at 3:13
