A GREAT Architecture for Edge-Based Graph Problems Like TSP

Autor: Lischka, Attila, Wu, Jiaming, Chehreghani, Morteza Haghir, Kulcsár, Balázs

In the last years, many neural network-based approaches have been proposed to tackle combinatorial optimization problems such as routing problems. Many of these approaches are based on graph neural networks (GNNs) or related transformers, operating o

Less Is More -- On the Importance of Sparsification for Transformers and Graph Neural Networks for TSP

Autor: Lischka, Attila, Wu, Jiaming, Basso, Rafael, Chehreghani, Morteza Haghir, Kulcsár, Balázs

Most of the recent studies tackling routing problems like the Traveling Salesman Problem (TSP) with machine learning use a transformer or Graph Neural Network (GNN) based encoder architecture. However, many of them apply these encoders naively by all

Quantifying white matter hyperintensity and brain volumes in heterogeneous clinical and low-field portable MRI

Brain atrophy and white matter hyperintensity (WMH) are critical neuroimaging features for ascertaining brain injury in cerebrovascular disease and multiple sclerosis. Automated segmentation and quantification is desirable but existing methods requir

Collaborative electric vehicle routing with meet points

Autor: Zhou, Fangting, Arvidsson, Ala, Wu, Jiaming, Kulcsar, Balazs

In this paper, we develop a profit-sharing-based optimal routing mechanism to incentivize horizontal collaboration among urban goods distributors. This paper investigates a collaborative routing problem for urban logistics, in which the exchange of g
