Fast Nonconvex SDP Solvers for Large-scale Power System State Estimation
Yu Lan, Hao Zhu, Xiaohong Guan
Fast power system state estimation (SE) solution is of paramount importance for achieving real-time decision making in power grid operations. Semidefinite programming (SDP) reformu…
Meta Reinforcement Learning with Task Embedding and Shared Policy
Lin Lan, Zhenguo Li, Xiaohong Guan +1
Despite significant progress, deep reinforcement learning (RL) suffers from data-inefficiency and limited generalization. Recent efforts apply meta-learning to learn a meta-learner…
A Memory-Efficient Sketch Method for Estimating High Similarities in Streaming Sets
Pinghui Wang, Yiyan Qi, Yuanming Zhang +4
Estimating set similarity and detecting highly similar sets are fundamental problems in areas such as databases, machine learning, and information retrieval. MinHash is a well-know…
Sampling Online Social Networks by Random Walk with Indirect Jumps
Junzhou Zhao, Pinghui Wang, John C. S. Lui +2
Random walk-based sampling methods are gaining popularity and importance in characterizing large networks. While powerful, they suffer from the slow mixing problem when the graph i…
A Fast Sampling Method of Exploring Graphlet Degrees of Large Directed and Undirected Graphs
Pinghui Wang, Xiangliang Zhang, Zhenguo Li +6
Exploring small connected and induced subgraph patterns (CIS patterns, or graphlets) has recently attracted considerable attention. Despite recent efforts on computing the number o…
Integrated Energy Exchange Scheduling for Multi-microgrid System with Electric Vehicles
Dai Wang, Xiaohong Guan, Jiang Wu +3
Electric vehicles (EVs) can be considered as flexible mobile battery storages in microgrids. For multiple microgrids in an area, coordinated scheduling on charging and discharging…
