Heuristics to allocate high-performance cloudlets for computation offloading in mobile ad hoc clouds
Bo Li,Yijian Pei,Hao Wu,Bin Shen +3 more
TL;DR: Experimental results show that it is not appropriate to map tasks only based on the expected bandwidth, execution time or the overall offloading time, and the expected completion time must be taken into account, so the MCTComm heuristic seems to be the best choice from the standpoint of the tradeoff between the complexity and the performance.
Journal ArticleDOI
Collaborative Topic Regression with social trust ensemble for recommendation in social media systems
TL;DR: This paper focuses on exploiting multi-sourced information (e.g. social networks, item contents and user feedbacks) to predict the ratings of users to items and make recommendations, and proposes corresponding approaches to learning the latent factors both of users and items.
Journal ArticleDOI
Unsupervised author disambiguation using Dempster---Shafer theory
Hao Wu,Bo Li,Yijian Pei,Jun He +3 more
TL;DR: An unsupervised Dempster–Shafer theory (DST) based hierarchical agglomerative clustering algorithm for author disambiguation tasks and achieves comparable performances to a supervised model, while does not prescribe any hand-labelled training data.
Proceedings ArticleDOI
An Improved Algorithm for Harris Corner Detection
Zhiyong Ye,Yijian Pei,Jihong Shi +2 more
TL;DR: An improved algorithm of Harris detection algorithm based on the neighboring point eliminating method is proposed that reduces the time of the detection, and makes the corners distributing more homogenous so that avoids too many corners stay together.
Proceedings ArticleDOI
The improved wavelet transform based image fusion algorithm and the quality assessment
TL;DR: The quality assessment of the image fusion, and summarize and quantitatively analysis the performance of algorithms proposed in the paper are studied.
