An Introduction to Machine Learning
Abstract
It would be a mistake to think that machine learning always requires examples with class labels. Far from it! Useful information can be gleaned even from examples whose classes are not known. This is sometimes called unsupervised learning, in contrast to the term supervised learning which is used when talking about induction from pre-classified examples.
