Researchers have applied sparse autoencoder-based mechanistic interpretability to a neutrino foundation model trained on IceCube data. They identified a validated atlas of physical concepts within the model's representation, though the direction head showed minimal reliance on it. An uncertainty head, trained on the same representation, successfully predicted the model's angular reconstruction error, improving median angular resolution by over sixfold at 20% selection efficiency. This work suggests mechanistic interpretability can uncover learned physics in model representations and aid in designing downstream tasks. AI
