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…

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.…
