A Large Collection of Real-world Pediatric Sleep Studies
Harlin Lee, Boyue Li, Shelly DeForte +4
Despite being crucial to health and quality of life, sleep -- especially pediatric sleep -- is not yet well understood. This is exacerbated by lack of access to sufficient pediatri…
Beyond Procrustes: Balancing-Free Gradient Descent for Asymmetric Low-Rank Matrix Sensing
Cong Ma, Yuanxin Li, Yuejie Chi
Low-rank matrix estimation plays a central role in various applications across science and engineering. Recently, nonconvex formulations based on matrix factorization are provably…
Vector-Valued Graph Trend Filtering with Non-Convex Penalties
Rohan Varma, Harlin Lee, Jelena Kovačević +1
This work studies the denoising of piecewise smooth graph signals that exhibit inhomogeneous levels of smoothness over a graph, where the value at each node can be vector-valued. W…
Harnessing Sparsity over the Continuum: Atomic Norm Minimization for Super Resolution
Yuejie Chi, Maxime Ferreira Da Costa
Convex optimization recently emerges as a compelling framework for performing super resolution, garnering significant attention from multiple communities spanning signal processing…
Quantized Spectral Compressed Sensing: Cramer-Rao Bounds and Recovery Algorithms
Haoyu Fu, Yuejie Chi
Efficient estimation of wideband spectrum is of great importance for applications such as cognitive radio. Recently, sub-Nyquist sampling schemes based on compressed sensing have b…
