Predicting Geographic Information with Neural Cellular Automata
Mingxiang Chen, Qichang Chen, Lei Gao +2
This paper presents a novel framework using neural cellular automata (NCA) to regenerate and predict geographic information. The model extends the idea of using NCA to generate/reg…
Dynamic Partial Removal: A Neural Network Heuristic for Large Neighborhood Search
Mingxiang Chen, Lei Gao, Qichang Chen +1
This paper presents a novel neural network design that learns the heuristic for Large Neighborhood Search (LNS). LNS consists of a destroy operator and a repair operator that speci…
Learn to Design the Heuristics for Vehicle Routing Problem
Lei Gao, Mingxiang Chen, Qichang Chen +3
This paper presents an approach to learn the local-search heuristics that iteratively improves the solution of Vehicle Routing Problem (VRP). A local-search heuristics is composed…
Measuring Road Network Topology Vulnerability by Ricci Curvature
Lei Gao, Xingquan Liu, Yu Liu +4
Describing the basic properties of road network systems, such as their robustness, vulnerability, and reliability, has been a very important research topic in the field of urban tr…
A Probabilistic Embedding Clustering Method for Urban Structure Detection
Xin Lin, Haifeng Li, Yan Zhang +3
Urban structure detection is a basic task in urban geography. Clustering is a core technology to detect the patterns of urban spatial structure, urban functional region, and so on.…
