Green's function based density estimation — •Peter Kovesarki, Ian C. Brock, and Adriana Elizabeth Nuncio Quiroz — Physikalisches Institut Universitaet Bonn, Bonn, Germany

A method was developed based on Green's function identities to estimate probability densities. This can be used for likelihood estimations and for binary classifications. It offers several advantages over neural networks, boosted decision trees and other, regression based classifiers. For exmaple, it is less prone to overtraining, and it is much easier to combine several samples. Some capabilities will be demonstrated using ATLAS data.
