Affine Invariant Ensemble Transform Methods to Improve Predictive Uncertainty in Neural Networks

2023-09-09 · Diksha Bhandari, Jakiw Pidstrigach, Sebastian Reich

We consider the problem of performing Bayesian inference for logistic regression using appropriate extensions of the ensemble Kalman filter. Two interacting particle systems are proposed that sample from an approximate posterior and prove quantitative convergence rates of these interacting particle systems to their mean-field limit as the number of particles tends to infinity. Furthermore, we apply these techniques and examine their effectiveness as methods of Bayesian approximation for quantifying predictive uncertainty in neural networks.

New affine invariant ensemble samplers and their dimensional scaling

2025-05-05 · Yifan Chen

We introduce new affine invariant ensemble samplers that are easy to construct and improve upon existing algorithms, especially for high-dimensional problems. Specifically, we propose a derivative-free ensemble side move…

Affine invariant triangulations

2020-11-04 · Prosenjit Bose, Pilar Cano, Rodrigo I. Silveira

We study affine invariant 2D triangulation methods. That is, methods that produce the same triangulation for a point set $S$ for any (unknown) affine transformation of $S$. Our work is based on a method by Nielson [A cha…

Affine Equivariant Networks Based on Differential Invariants

2024-01-01 · CVPR 2024 1 · Yikang Li, Yeqing Qiu, Yuxuan Chen, Lingshen He 외

Convolutional neural networks benefit from translation equivariance achieving tremendous success. Equivariant networks further extend this property to other transformation groups. However most existing methods requir…

Improving the Robustness of Adversarial Attacks Using an Affine-Invariant Gradient Estimator

Naturally Combined Shape-Color Moment Invariants under Affine Transformations

2017-05-31 · Ming Gong, You Hao, Hanlin Mo, Hua Li

We proposed a kind of naturally combined shape-color affine moment invariants (SCAMI), which consider both shape and color affine transformations simultaneously in one single system. In the real scene, color and shape de…
