The IceCube Neutrino Observatory is a large neutrino detector built deep in the Antarctic ice at the South Pole. The Advanced Northern Track Selection (ANTS) framework uses a graph convolutional neural network to select neutrino-induced muon tracks. These events have different topologies and signatures within the detector, such as through-going, starting, skimming tracks as well as remaining background from cosmic-ray induced muons and cascades e.g. related to electron neutrinos. In this work, we perform the classification of these event topologies using the ANTS framework, providing an event-wise probability for each topology. This classification enables dedicated handling of these topologies in further analyses.
