This article at developer.com, gives first hand information about creating neural networks in PHP language. Artificial neural networks are developed mostly in high-level programming languages such as C or C++, So reading about them in PHP is a refreshing experience.
What are Neural Networks?
The network works similarly to the human brain: it is comprised of neurons that communicate with each other and provide valuable outputs. Although just a model — and not even close to human thinking — artificial neural networks have been used in prediction, classification, and decision-support systems, as well as in optical character recognition and many other applications.
