Query: A real bad one

This is the wrong book for any student or practioner of neural nets. It does not go into the theory of neural networks enough, though it does explain back-propagation methods (superficially though) it doesn't even provide any helpful codes beyond the very rudimentry, so whether you are looking for a sold foundation on NNs or a quick fix (read code), this book provides neither. For a solid foundation, I would recommend Simon Haykin's book.
