Eigenfaces is a much better approach to face recognition than neural networks. The promise of neueral networks for large scale problems in general has never panned out, despite some spectacular results in some situations.

The coding of a simple neural network is enticingly easy. However, the choice of weights can become a problem that rivals the original problem.

Eigenfaces is much more mathematically challenging. You need to know eigenvalues and eigenvectors and in general matrix algebra. But, once you understand the basic concepts, you will find eigenfaces amazingly intuitive.
