Abstract
This chapter describes how boosted decision trees are created and applied in order to separate single top quark events from background events, and how the single top quark production cross section is measured using the boosted decision tree output distributions. Measurements of the signal significance and the CKM matrix element \(|V_{tb}|\) are also presented, as well as several cross checks of the measurements.
