uBoost: a boosting method for producing uniform selection efficiencies from multivariate classifiers
Stevens, Justin, Williams, Michael · DSpace@MIT (Massachusetts Institute of Technology) · 2013
The use of multivariate classifiers, especially neural networks and decision trees, has become commonplace in particle physics. Typically, a series of classifiers is trained rather than just one to enhance the performance; this is known as boosting. This paper presents a novel method of boosting that produces a uniform selection efficiency in a selected multivariate space. Such a technique is well suited for amplitude analyses or other situations where optimizing a single integrated figure of merit is not what is desired.
