A Hybrid Approach to Privacy-Preserving Federated Learning
Stacey Truex, Nathalie Baracaldo, Ali Anwar +4
Federated learning facilitates the collaborative training of models without the sharing of raw data. However, recent attacks demonstrate that simply maintaining data locality durin…
Efficient Non-parametric Bayesian Hawkes Processes
Rui Zhang, Christian Walder, Marian-Andrei Rizoiu +1
In this paper, we develop an efficient nonparametric Bayesian estimation of the kernel function of Hawkes processes. The non-parametric Bayesian approach is important because it pr…
Uplink Cooperative NOMA for Cellular-Connected UAV
Weidong Mei, Rui Zhang
Aerial-ground interference mitigation is a challenging issue in the cellular-connected unmanned aerial vehicle (UAV) communications. Due to the strong line-of-sight (LoS) air-to-gr…
Artwork Identification from Wearable Camera Images for Enhancing Experience of Museum Audiences
Rui Zhang, Yusuf Tas, Piotr Koniusz
Recommendation systems based on image recognition could prove a vital tool in enhancing the experience of museum audiences. However, for practical systems utilizing wearable camera…
Cluster-based Wireless Energy Transfer for Low Complex Energy Receivers
Samith Abeywickrama, Tharaka Samarasinghe, Chau Yuen +1
This paper proposes a novel channel estimation method and a cluster-based opportunistic scheduling policy, for a wireless energy transfer (WET) system consisting of multiple low-co…
A framework with updateable joint images re-ranking for Person Re-identification
Mingyue Yuan, Dong Yin, Jingwen Ding +4
Person re-identification plays an important role in realistic video surveillance with increasing demand for public safety. In this paper, we propose a novel framework with rules of…
Collaborative Learning for Weakly Supervised Object Detection
Jiajie Wang, Jiangchao Yao, Ya Zhang +1
Weakly supervised object detection has recently received much attention, since it only requires image-level labels instead of the bounding-box labels consumed in strongly supervise…
Museum Exhibit Identification Challenge for Domain Adaptation and Beyond
Piotr Koniusz, Yusuf Tas, Hongguang Zhang +3
In this paper, we approach an open problem of artwork identification and propose a new dataset dubbed Open Museum Identification Challenge (Open MIC). It contains photos of exhibit…
#DebateNight: The Role and Influence of Socialbots on Twitter During the 1st 2016 U.S. Presidential Debate
Marian-Andrei Rizoiu, Timothy Graham, Rui Zhang +3
Serious concerns have been raised about the role of 'socialbots' in manipulating public opinion and influencing the outcome of elections by retweeting partisan content to increase…
Matrix completion with deterministic pattern - a geometric perspective
Alexander Shapiro, Yao Xie, Rui Zhang
We consider the matrix completion problem with a deterministic pattern of observed entries. In this setting, we aim to answer the question: under what condition there will be (at l…
