Neural Networks in PHP

PHPclasses.org recently published an article about a PHP implementation of Neural Networks by neuralmesh.com. The great thing about this is you don't really need to understand the inner workings of NNs but you can just use their framework to get things done. This might come in very handy in the future: http://www.phpclasses.org/blog/post/119-Neural-Networks-in-PHP.html

Just one thing I noticed, their Connect 4 NN doesn't learn very well at all.
