Title: Tau Neutrino Appearance in the IceCube Upgrade


The coming IceCube Upgrade will give us the unique ability to probe the low energy region of the atmospheric neutrinos and enable better measurements of neutrino oscillation than ever before. Observing tau neutrinos event by event would make it possible to make more accurate predictions and bring us closer to answering the big questions within neutrino physics.

This thesis uses a graph neural network approach to classifying tau neutrino events, and explores the reasons why this type of analysis is still out of reach for the IceCube experiment even with first-class machine learning methods.
