Description

The basic signal of the ATLAS calorimeters are three-dimensional clusters of topologically connected cell signals formed by following signal significance patterns. These topo-clusters provide measures of their shape, location and signal character which are employed to apply a local hadronic calibration. The corresponding multi-dimensional calibration functions are determined by training neural networks to learn the basic topo-cluster response. Selected results from this approach are compared to the standard method using look-up tables. Significant improvements are found with respect to the signal linearity and resolution.
