Conditional Deformable Image Registration with Spatially-Variant and Adaptive Regularization

no code implementations19 Mar 2023 Yinsong Wang, Huaqi Qiu, Chen Qin

The proposed method introduces a spatially-variant regularization and learns its effect of achieving spatially-adaptive regularization by conditioning the registration network on the hyperparameter matrix via CSAIN.

TAKDE: Temporal Adaptive Kernel Density Estimator for Real-Time Dynamic Density Estimation

no code implementations15 Mar 2022 Yinsong Wang, Yu Ding, Shahin Shahrampour

Kernel density estimation is arguably one of the most commonly used density estimation techniques, and the use of "sliding window" mechanism adapts kernel density estimators to dynamic processes.

Learning from Non-Random Data in Hilbert Spaces: An Optimal Recovery Perspective

no code implementations5 Jun 2020 Simon Foucart, Chunyang Liao, Shahin Shahrampour, Yinsong Wang

Then, for any Hilbert space, we show that Optimal Recovery provides a formula which is user-friendly from an algorithmic point-of-view, as long as the hypothesis class is linear.

ORCCA: Optimal Randomized Canonical Correlation Analysis

no code implementations11 Oct 2019 Yinsong Wang, Shahin Shahrampour

We prove that this method, called ORCCA, can outperform (in expectation) the corresponding Kernel CCA with a default kernel.
