Active Data Acquisition with Side Information via Discrete Diffusion Priors
An Vuong, Thinh Nguyen
Acquiring data is costly: higher measurement fidelity costs power and storage and risks collecting irrelevant content, while aggressive cost reduction can discard information that…
Cross-Domain Lossy Compression via Constrained Minimum Entropy Coupling
Nam Nguyen, Hassan Tavakoli, An Vuong +2
This paper studies cross-domain lossy compression through the lens of minimum entropy coupling (MEC) with rate and classification constraints. In this setting, an encoder observes…
On Symbol Error Probability-based Beamforming in MIMO Gaussian Wiretap Channels
Nam Nguyen, An Vuong, Thuan Nguyen +1
This paper investigates beamforming schemes designed to minimize the symbol error probability (SEP) for an authorized user while guaranteeing that the likelihood of an eavesdropper…
Perception-based multiplicative noise removal using SDEs
An Vuong, Thinh Nguyen
Multiplicative noise, also known as speckle or pepper noise, commonly affects images produced by synthetic aperture radar (SAR), lasers, or optical lenses. Unlike additive noise, w…
