I found Lindsay I. Smith's "A tutorial on Principal Components Analysis" [1] really useful because it covers the mathematics behind PCA but gives enough linear algebra background for it to be understandable by those with distant or weak math backgrounds (e.g., me).

Thanks, that is incredibly interesting, especially the example at the end relating to facial recognition.
