Optimal Symmetries in Binary Classification
Quick summary
arXiv:2408.08823v2 Announce Type: replace-cross Abstract: We develop a theoretical foundation for designing group-equivariant neural networks that align the choice of symmetries with the underlying probability distributions of the data. Utilising the general structure of fibre decompositions on the domain under group equivariant maps and its relation to that of the likelihood ratio, we present a theoretical framework for identifying group actions that maintain optimal classification performance via the Neyman-Pearson lemma. This provides a unified methodology for improving classification accur
