To create the graphG, we propose a two-step procedure. In the first step, we use a routing service to find route distances between all pairs of locations. Assuming that the distances are symmetric, we terminate with an undirected fully connected graphG∗=(L,[L]2,D∗), where[L]2is...
倘若\sum_k \left| B_k\right|很大的话,那么机器之间数据交换的代价可能非常昂贵。因此,不同于旨在最小化edge cuts的主流图分割算法,该文章提出了一个最小化各个簇在簇外的一阶邻居数量的图分割算法。显然,最小化这个目标是一个NP-hard的问题,因此作者们提出了一个贪婪策略,使得\sum_k \left| B_k\right...

When dealing with NP-hard optimization problems, it is natural to take a look at special cases. In this section we give a polynomial time algorithm to find the partition with the maximum density when the graph is a tree. Partitions with maximum density are called optimal partitions. In the ...

例如Semi-Supervised Classification with Graph Convolutional Networks一文中的GCN形式,其实是二阶Chebyshev多项式推导出的特例。 在我最近发表的一篇论文中:就是用这种GCN形式作为基于有限检测器的路网规模交通流量估计问题(一种特殊的时空矩阵填充问题)的baseline,即原文4.2节部分的CGMC模型。感兴趣的朋友可以阅读如下的...
Observing that the graph has to be loaded into the cluster, we ask if the partitioning can be done at the same time with a lightweight streaming algorithm. We propose natural, simple heuristics and compare their performance to hashing and METIS, a fast, offline heuristic. We show on a ...
They are credited with having simple design capability, scalability and robustness. There are other algorithms based on the natural swarm behavior, such as bee colony, flocks of birds, and schools of fish. However, the ACO is categorized under ant-based techniques under SI. The Ant-based ...
Then, we study the quality of random partitioning, which serves as a baseline for other partitioning algorithms. 3.1 Problem Definitions First, we need to decide how to measure the goodness of a par- titioning. A natural goodness measure is the size of edge cut, that is, edges whose two ...
