Sparse Activations as Conformal Predictors

AISTATS 2025poster

Conformal prediction is a distribution-free framework for uncertainty quantification that replaces point predictions with sets, offering marginal coverage guarantees (i.e., ensuring that the sets contain the true label with a specified probability, in expectation). In this paper, we uncover a novel…

Adaptive Relaxed ADMM: Convergence Theory and Practical Implementation

CVPR 2017poster

Many modern computer vision and machine learning applications rely on solving difficult optimization problems that involve non-differentiable objective functions and constraints. The alternating direction method of multipliers (ADMM) is a widely used approach to solve such problems. Relaxed ADMM is…

Region-Based Correspondence Between 3D Shapes via Spatially Smooth Biclustering

ICCV 2017poster

Region-based correspondence (RBC) is a highly relevant and non-trivial computer vision problem. Given two 3D shapes, RBC seeks segments/regions on these shapes that can be reliably put in correspondence. The problem thus consists both in finding the regions and determining the correspondences betwee…
