A Gaussian Perspective for Distributional Discrepancy in Generative Diffusion Models
Qiang Sun, H. Vincent Poor, Wenyi Zhang
This paper introduces an analytical approach to quantifying and optimizing the distributional discrepancy in generative diffusion models. For a multivariate Gaussian source, we exp…

PAC Learnability for Reliable Communication over Discrete Memoryless Channels
Jiakun Liu, Wenyi Zhang, H. Vincent Poor
In practical communication systems, knowledge of channel models is often absent, and consequently, transceivers need be designed based on empirical data. In this work, we study dat…

On Minimax Robust Detection of Stationary Gaussian Signals in White Gaussian Noise
Wenyi Zhang, H. Vincent Poor
The problem of detecting a wide-sense stationary Gaussian signal process embedded in white Gaussian noise, where the power spectral density of the signal process exhibits uncertain…
