Geometric Moment Alignment for Domain Adaptation via Siegel Embeddings

Shayan Gharib, Marcelo Hartmann, Arto Klami

We address the problem of distribution shift in unsupervised domain adaptation with a moment-matching approach. Existing methods typically align low-order statistical moments of th…

Simplex-to-Euclidean Bijections for Categorical Flow Matching

Bernardo Williams, Victor M. Yeom-Song, Marcelo Hartmann +1

We propose a method for learning and sampling from probability distributions supported on the simplex. Our approach maps the open simplex to Euclidean space via smooth bijections,…

Learning Geometry and Topology via Multi-Chart Flows

Hanlin Yu, Søren Hauberg, Marcelo Hartmann +2

Real world data often lie on low-dimensional Riemannian manifolds embedded in high-dimensional spaces. This motivates learning degenerate normalizing flows that map between the amb…
