1 Computer Science Department, Technische Universität [...] separation step is the high imbalance between signal (gamma rays) and background noise, ranging from 1:1000 up to 1:10000 and worse, which implies large amounts of data that need to be recorded for a well- founded [...] hadronic background. As the showers are distinct events, this boils down to finding some model
M : S → {−1,+1} that maps a recorded shower S ∈ S represented by a set of features to one of the two possible classes …
