Riemannian Archetypal Analysis: Interpretable non-linear data analysis on deformed star distributions
arXiv:2605.24113v1 Announce Type: new Abstract: Classical archetypal analysis is appealing for its interpretability, but its linear geometry can limit performance on data with strongly non-linear structure; at the same time, existing neural extensions improve flexibility while often weakening the geometric meaning of archetypes and interpolations. In this work, we develop a Riemannian version of archetypal analysis based on data-driven pullback geometry for real-valued data, with the goal of combining the interpretability of classical archetypal analysis with the expressive power of modern non
This research builds on classical archetypal analysis and neural extensions, reflecting a current drive to enhance interpretability in advanced AI models while maintaining performance.
Improved interpretable non-linear data analysis is crucial for developing more robust and trustworthy AI systems, particularly in sensitive domains, and for understanding complex datasets.
This work introduces a new method for combining the interpretability of classical archetypal analysis with the flexibility of modern opaque models through Riemannian geometry.
