Does anyone have an example of a backpropagation neural network?

Question

PHP

I'm looking for a simple example in a language with C-shaped syntax, without a bunch of included files in the project, without abstract mess, like a separate class for each neuron, layer, etc.
Ideally, this will be a regular main.c with a set of functions and a length of 200-300 lines of code

Answer 1

I ask you to pay your attention to this book:
Artificial Intelligence Programming in Apps...
It has exactly what you are looking for - no OOP, no third-party libraries. There is a whole chapter on the algorithm for training neural networks with back propagation + conveniently readable listings in pure si.
