Description
The directional reconstruction of IceCube neutrinos, including the estimation of uncertainties, is essential for point source searches. In recent years, per-event posterior estimation with normalizing flows has emerged as a powerful reconstruction technique for the direction. The first part of the talk will give an introduction to normalizing flows. The second part will describe recent results in their application to IceCube directional reconstruction in combination with transformers, which yields new state-of-the-art results for the angular resolution of the two main event topologies in IceCube: showers and tracks.
