Nonisotropic Gaussian Diffusion for Realistic 3D Human Motion Prediction

Cecilia Curreli, Dominik Muhle, Abhishek Saroha +3

Probabilistic human motion prediction aims to forecast multiple possible future movements from past observations. While current approaches report high diversity and realism, they o…

Sparse Views, Near Light: A Practical Paradigm for Uncalibrated Point-light Photometric Stereo

Mohammed Brahimi, Bjoern Haefner, Zhenzhang Ye +2

Neural approaches have shown a significant progress on camera-based reconstruction. But they require either a fairly dense sampling of the viewing sphere, or pre-training on an exi…

Enhancing Hypergradients Estimation: A Study of Preconditioning and Reparameterization

Zhenzhang Ye, Gabriel Peyré, Daniel Cremers +1

Bilevel optimization aims to optimize an outer objective function that depends on the solution to an inner optimization problem. It is routinely used in Machine Learning, notably f…

Joint Deep Multi-Graph Matching and 3D Geometry Learning from Inhomogeneous 2D Image Collections

Zhenzhang Ye, Tarun Yenamandra, Florian Bernard +1

Graph matching aims to establish correspondences between vertices of graphs such that both the node and edge attributes agree. Various learning-based methods were recently proposed…

Combinatorial Preconditioners for Proximal Algorithms on Graphs

Thomas Möllenhoff, Zhenzhang Ye, Tao Wu +1

We present a novel preconditioning technique for proximal optimization methods that relies on graph algorithms to construct effective preconditioners. Such combinatorial preconditi…
