23 April 2006

We present a framework to quantitatively measure trust, model trust propagation, and defend trust evaluation systems against malicious attacks. Expand

FusionGAN: A generative adversarial network for infrared and visible image fusion

Jiayi Ma, Wei Yu, Pengwei Liang, C. Li, J. Jiang
Computer Science
Inf. Fusion
1 August 2019

This paper proposes a novel method to fuse these two types of information using a generative adversarial network, termed as FusionGAN, to generate clear and clean fused images which do not suffer from noise caused by upsampling of infrared information. Expand

We explore the application of machine learning techniques to the problem of content-based image retrieval (CBIR). Expand

Optimization of Heterogeneous Coded Caching

A. M. Daniel, Wei Yu
Computer Science, Mathematics
IEEE Transactions on Information Theory
14 August 2017

This paper aims to provide an optimization framework for coded caching that accounts for various heterogeneous aspects of practical systems that have yet to be considered in the literature. Expand

On the energy efficiency of cooperative communications in wireless sensor networks

A. Sadek, Wei Yu, K. R. Liu
Computer Science

1 December 2009

Cooperative communications represent a potential candidate to combat the effects of channel fading and to increase the transmit energy efficiency in wireless sensor networks . Expand

Cooperation Enforcement in Autonomous MANETs under Noise and Imperfect Observation

Zhu Ji, Wei Yu, K. R. Liu
Computer Science
3rd Annual IEEE Communications Society on Sensor…
2006

We focus on cooperation enforcement in autonomous mobile ad hoc networks under noise and imperfect observation and study the basic packet-forwarding function using the repeated game models with imperfect information. Expand

Spatial Deep Learning for Wireless Scheduling

Wei Cui, K. Shen, Wei Yu
Computer Science
IEEE Global Communications Conference (GLOBECOM)
4 August 2018

We show that it is possible to bypass the channel estimation stage altogether and to use a deep neural network to produce a near optimal schedule based solely on geographic locations of the transmitters and receivers in the network. Expand
