Panoramic Video Separation with Online Grassmannian Robust Subspace Estimation
Published in 2019 Proceedings of the IEEE/CVF International Conference on Computer Vision (ICCV) - Workshop, 2019
In this work, we propose a new total variation (TV)-regularized robust principal component analysis (RPCA) algorithm for panoramic video data with incremental gradient descent on the Grassmannian.

Online Tensor Completion and Free Submodule Tracking with the t-SVD
Published in 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
We propose a new online algorithm, called TOUCAN, for the tensor completion problem of imputing missing entries of a low tubal-rank tensor using the tensor-tensor product (t- product) and tensor singular value decomposition (t-SVD) algebraic framework.

HePPCAT: Probabilistic PCA for Data with Heteroscedastic Noise
Published in IEEE Transactions on Signal Processing, Vol. 69, 2021
This paper develops a probabilistic PCA variant that estimates and accounts for this heterogeneity by incorporating it in the statistical model.

Grassmannian Optimization for Online Tensor Completion and Tracking with the t-SVD
Published in IEEE Transactions on Signal Processing, Vol. 70, 2022, 2022
We propose a new fast streaming algorithm for the tensor completion problem of imputing missing entries of a low-tubal-rank tensor using the tensor singular value decomposition (t-SVD) algebraic framework.

A Semidefinite Relaxation for Sums of Heterogeneous Quadratics on the Stiefel Manifold
Published in arXiv, 2022
We study the maximization of sums of heterogeneous quadratic functions over the Stiefel manifold, a nonconvex problem that arises in several modern signal processing and machine learning applications such as heteroscedastic probabilistic principal component analysis (HPPCA).
