Balanced Districting on Grid Graphs with Provable Compactness and Contiguity
Cyrus Hettle, Shixiang Zhu, Swati Gupta +1
Given a graph with vertex weights and a desired number of parts , the goal in graph partitioning problems is to partition the vertex set V into parts $V_1,\ld…
Goodness-of-Fit Test for Mismatched Self-Exciting Processes
Song Wei, Shixiang Zhu, Minghe Zhang +1
Recently there have been many research efforts in developing generative models for self-exciting point processes, partly due to their broad applicability for real-world application…
Imitation Learning of Neural Spatio-Temporal Point Processes
Shixiang Zhu, Shuang Li, Zhigang Peng +1
We present a novel Neural Embedding Spatio-Temporal (NEST) point process model for spatio-temporal discrete event data and develop an efficient imitation learning (a type of reinfo…
Learning Temporal Point Processes via Reinforcement Learning
Shuang Li, Shuai Xiao, Shixiang Zhu +3
Social goods, such as healthcare, smart city, and information networks, often produce ordered event data in continuous time. The generative processes of these event data can be ver…
Crime Event Embedding with Unsupervised Feature Selection
Shixiang Zhu, Yao Xie
We present a novel event embedding algorithm for crime data that can jointly capture time, location, and the complex free-text component of each event. The embedding is achieved by…
