PCA_demo.m is a demonstration of Principal Component Analysis in action and is based on Ian Goodfellow's Deep Learning Book.
PCA.m is a function that will reduce the data you feed it using the smallest amount of dimensions necessary to represent it while preserving a reconstruction error below a threshold you can choose.
