"A new technique for separating the wheat
from the chaff in data."
Byron Roe, University of Michigan


Abstract:

In examining data, we are often faced with the problem of classifying it into categories, e.g. "signal" and "background". A new technique for classifying data is presented: boosted decision trees. This technique is compared with the older artificial neural net (ANN) technique using the mini-BooNE neutrino oscillation experiment as a test bed. The new technique does a better job of classification of data. Furthermore, it requires less tuning of parameters, generally seems more robust and can handle many more classification variables than an ANN. We expect this technique to have wide applications within physics, often supplanting ANN techniques currently in use.
