I'm interested in creating intelligent software in PHP, but I do not know where to start, as there is little material about it.
What do neural networks and artificial intelligence have in common or how do they work together?
Where to begin developing systems with AI in PHP? Any example (code) to take as a starting point?
"In the first place, the paradigm of neurocomputation is motivated by cognitive abilities of biological neural networks, inspired by the knowledge of neuroscience. The foundations of ANNs are the model of a neuron, network topology, and learning paradigms. O model of McCulloch and Pitts serves as the basic model of a neuron artificial.
Artificial Neuraus Networks are very useful in expert systems, that is, in replicate and repeat procedures. "¹ (RAUBER, T. W.)
To begin, I suggest trying to understand a little bit about how the human brain works and how cognitive analysis works. It would be interesting also mathematical and physical knowledge because many equations are complex.
One of the preconceived languages for AI is Prolog that can help with predicative programming. According to Wikipedia:
"Prolog is a programming language that fits the paradigm of Programming in Mathematical Logic. "
NOTE: Remember that Neural Network is a expert architecture! Applying it in an environment with multiple functionality can work and the use of Fuzzy logic is indicated.
"RNA has numerous algorithms for pattern recognition: Kohonen, Perceptron, Adaline, Backpropagation and many others, each with its specificity. The main advantage of using the Backpropagation is that it works with multilayers and resolves "non-linearly separable" problems and some algorithms do not solve.
In short, a "non-linearly separable" problem is one where we can separate two distinct classes in the two-dimensional Cartesian axis just drawing a straight line. "² (DEV Media)
A widely used form of the neural network is the Backpropagation Backpropagation - DEV Media
