How can the shaky separate views of a panel of dolts be combined into a single opinion that is very likely to be correct? That this possibility of garnering wisdom from a council of fools can be harnessed and used to advantage may seem far-fetched and implausible, especially in real life. Nevertheless, this unlikely strategy turns out to form the basis of boosting, an approach to machine learning that is the topic of this book. Indeed, at its core, boosting solves hard machine-learning problems by forming a very smart committee of grossly incompetent but carefully selected members. To see how this might work in the context of machine learning, consider the problem of filtering out spam, or junk email. Spam is a modern-day nuisance, and one that is ideally handled by highly accurate filters that can identify and remove spam from the flow of legitimate email. Thus, to build a spam filter, the main problem is to create a method by which a computer can automatically categorize email as spam (junk) or ham (legitimate). The machine learning approach to this problem prescribes that we begin by gathering a collection of examples of the two classes, that is, a collection of email messages which have been labeled, presumably by a human, as spam or ham. The purpose of the machine learning algorithm is to automatically produce from such data a prediction rule that can be used to reliably classify new examples (email messages) as spam or ham. For any of us who has ever been bombarded with spam, rules for identifying spam or ham will immediately come to mind. For instance, if it contains the word Viagra, then it is probably spam. Or, as another example, email from one's spouse is quite likely to be ham. Such individual rules of thumb are far from complete as a means of separating spam from ham. A rule that classifies all email containing Viagra as spam, and all other email as ham, will very often be wrong. On the other hand, such a rule is undoubtedly telling us something useful and nontrivial, and its accuracy, however poor, will nonetheless be significantly better than simply guessing entirely at random as to whether each email is spam or ham.
