Layered Graph Embedding for Entity Recommendation using Wikipedia in the Yahoo! Knowledge Graph
Chien-Chun Ni, Kin Sum Liu, Nicolas Torzec
In this paper, we describe an embedding-based entity recommendation framework for Wikipedia that organizes Wikipedia into a collection of graphs layered on top of each other, learn…
Topology Based Scalable Graph Kernels
Kin Sum Liu, Chien-Chun Ni, Yu-Yao Lin +1
We propose a new graph kernel for graph classification and comparison using Ollivier Ricci curvature. The Ricci curvature of an edge in a graph describes the connectivity in the lo…
Community Detection on Networks with Ricci Flow
Chien-Chun Ni, Yu-Yao Lin, Feng Luo +1
Many complex networks in the real world have community structures -- groups of well-connected nodes with important functional roles. It has been well recognized that the identifica…
Network Alignment by Discrete Ollivier-Ricci Flow
Chien-Chun Ni, Yu-Yao Lin, Jie Gao +1
In this paper, we consider the problem of approximately aligning/matching two graphs. Given two graphs and , the objective is to map node…
Decentralized Trajectory Tracking Using Homology and Hodge Decomposition in Sensor Networks
Xiaotian Yin, Yu-Yao Lin, Chien-Chun Ni +5
With the recent development of localization and tracking systems for both indoor and outdoor settings, we consider the problem of sensing, representing and analyzing human movement…
Robot Coverage Path Planning for General Surfaces Using Quadratic Differentials
Yu-Yao Lin, Chien-Chun Ni, Na Lei +2
Robot Coverage Path planning (i.e., provide full coverage of a given domain by one or multiple robots) is a classical problem in the field of robotics and motion planning. The goal…
Capacitated Kinetic Clustering in Mobile Networks by Optimal Transportation Theory
Chien-Chun Ni, Zhengyu Su, Jie Gao +1
We consider the problem of capacitated kinetic clustering in which mobile terminals and base stations with respective operating capacities are given. The task is to assign…
Ricci Curvature of the Internet Topology
Chien-Chun Ni, Yu-Yao Lin, Jie Gao +2
Analysis of Internet topologies has shown that the Internet topology has negative curvature, measured by Gromov's "thin triangle condition", which is tightly related to core conges…
