Machine learning theory papers explore convexity, ratio losses, and spurious correlations

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 7 sources

Two new arXiv papers explore theoretical aspects of machine learning loss functions. One paper surveys ratio-based loss functions, examining their properties like continuity and convexity to enable future research. The other paper characterizes conditions for strong universal Bayes-consistency in learning with general metric losses, resolving an open problem in the field. AI
