Most Machine Learning/Neural Network code is in python or C/C++ not PHP. Something like this would be a good starting point if moving to Python is not an option.
- jacques_chester 14y agoA perceptron is 1. simple to code up and 2. not very useful.[1] You still need to pick the sort of neural network you're building (there are literally hundreds in the literature) before anything of consequence is going to happen. The reason to use C/C++ libraries is that neural nets are slow. Slow slow slow. Computational intelligence / nature inspired computing is extremely cool, but the smart thing is to avoid it like the plague unless it is the only workable alternative. [1] To the point that neural network research came to a screeching halt for some time when it was proved that a perceptron cannot perform a XOR on inputs.
- illicium 14y ago>a perceptron cannot perform a XOR on inputs Multi-layer perceptron networks, however, can.
- jacques_chester 14y agoRight. According to my old notes you need: * at least one layer to handle linearly separable functions, * at least one hidden layer to handle continuous functions, and * at least two hidden layers to solve continuous and discontinuous functions.
