GTEA: Inductive Representation Learning on Temporal Interaction Graphs via Temporal Edge Aggregation
Siyue Xie, Yiming Li, Da Sun Handason Tam +5
In this paper, we propose the Graph Temporal Edge Aggregation (GTEA) framework for inductive learning on Temporal Interaction Graphs (TIGs). Different from previous works, GTEA mod…
Identifying Illicit Accounts in Large Scale E-payment Networks -- A Graph Representation Learning Approach
Da Sun Handason Tam, Wing Cheong Lau, Bin Hu +3
Rapid and massive adoption of mobile/ online payment services has brought new challenges to the service providers as well as regulators in safeguarding the proper uses such service…
Online Job Scheduling with Redundancy and Opportunistic Checkpointing: A Speedup-Function-Based Analysis
Huanle Xu, Gustavo de Veciana, Wing Cheong Lau +1
In a large-scale computing cluster, the job completions can be substantially delayed due to two sources of variability, namely, variability in the job size and that in the machine…
Robust and Fast Decoding of High-Capacity Color QR Codes for Mobile Applications
Zhibo Yang, Huanle Xu, Jianyuan Deng +2
The use of color in QR codes brings extra data capacity, but also inflicts tremendous challenges on the decoding process due to chromatic distortion, cross-channel color interferen…
Task-Cloning Algorithms in a MapReduce Cluster with Competitive Performance Bounds
Huanle Xu, Wing Cheong Lau
Job scheduling for a MapReduce cluster has been an active research topic in recent years. However, measurement traces from real-world production environment show that the duration…
Optimization for Speculative Execution of Multiple Jobs in a MapReduce-like Cluster
Huanle Xu, Wing Cheong Lau
Nowadays, a computing cluster in a typical data center can easily consist of hundreds of thousands of commodity servers, making component/ machine failures the norm rather than exc…
Secure Friend Discovery via Privacy-Preserving and Decentralized Community Detection
Pili Hu, Sherman S. M. Chow, Wing Cheong Lau
The problem of secure friend discovery on a social network has long been proposed and studied. The requirement is that a pair of nodes can make befriending decisions with minimum i…
SNSAPI: A Cross-Platform Middleware for Rapid Deployment of Decentralized Social Networks
Pili Hu, Qijiang Fan, Wing Cheong Lau
In this paper, we present the design, implementation and our year-long maintenance experience of SNSAPI, a Python-based middleware which unifies the interfaces and data structures…
A Survey and Taxonomy of Graph Sampling
Pili Hu, Wing Cheong Lau
Graph sampling is a technique to pick a subset of vertices and/ or edges from original graph. It has a wide spectrum of applications, e.g. survey hidden population in sociology [54…
Localized Algorithm of Community Detection on Large-Scale Decentralized Social Networks
Pili Hu, Wing Cheong Lau
Despite the overwhelming success of the existing Social Networking Services (SNS), their centralized ownership and control have led to serious concerns in user privacy, censorship…
