New methods for the application of neural networks in the presence of systematic uncertainties — Simon Jörger¹, Günter Quast¹, Roger Wolf¹, and •Stefan Wunsch^1,2 — ¹KIT — ²CERN

In this talk, we introduce new methods for the application of neural networks in the presence of systematic uncertainties, common in HEP analysis. We discuss a new technique to identify those features of the multi-dimensional input space, which the response of the network is most sensitive to, as a crucial input to the discussion of the propagation of systematic uncertainties onto the neural network output and therefore the measurement. A second method is presented to penalize such propagations of systematic variations controlling the impact of systematic uncertainties on the measurement.
