Ordinal Classification in DSEA — •Jan Philipp Jäkel — Technische Universität Dortmund

DSEA+, or Dortmund Spectrum Estimation Algorithm, is an improved version of the original DSEA algorithm built for unfolding energy distributions in the area of neutrino astronomy. It interprets deconvolution as a multinomial classification problem enabling reconstruction of binned spectra. Several classification models can be embedded for this purpose, but all of them treat the energy bins and their associated reconstructed values as unrelated quantities, leading to loss of generality. The need for ordinal classification arises, that preserves the ordinal inherent nature of the energy spectra. In this talk, we propose a built on version of DSEA+ utilizing this approach with the result of refined reconstruction and the capability of inspecting probability distributions of individual events detected.
