An Optimal Transport Approach to the Computation of the LM Rate
Wenhao Ye, Huihui Wu, Shitong Wu +4
Mismatch capacity characterizes the highest information rate for a channel under a prescribed decoding metric, and is thus a highly relevant fundamental performance metric when dea…
An Indirect Rate-Distortion Characterization for Semantic Sources: General Model and the Case of Gaussian Observation
Jiakun Liu, Shuo Shao, Wenyi Zhang +1
A new source model, which consists of an intrinsic state part and an extrinsic observation part, is proposed and its information-theoretic characterization, namely its rate-distort…
Improved Receivers for Optical Wireless OFDM: An Information Theoretic Perspective
Xiaozhen Liu, Jing Zhou, Nuo Huang +1
We consider performance enhancement of asymmetrically-clipped optical orthogonal frequency division multiplexing (ACO-OFDM) and related optical OFDM schemes, which are variations o…
On the Capacity of MISO Optical Intensity Channels With Per-Antenna Intensity Constraints
Ru-Han Chen, Longguang Li, Jian Zhang +2
This paper investigates the capacity of general multiple-input single-output (MISO) optical intensity channels (OICs) under per-antenna peak- and average-intensity constraints. We…
Decentralized Federated Learning: Balancing Communication and Computing Costs
Wei Liu, Li Chen, Wenyi Zhang
Decentralized stochastic gradient descent (SGD) is a driving engine for decentralized federated learning (DFL). The performance of decentralized SGD is jointly influenced by inter-…
A Rate-Distortion Framework for Characterizing Semantic Information
Jiakun Liu, Wenyi Zhang, H. Vincent Poor
A rate-distortion problem motivated by the consideration of semantic information is formulated and solved. The starting point is to model an information source as a pair consisting…
