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...
We consider the problem of partitioning the set of nodes in a graph in at most p classes, such that the sum of node weights in any class is not greater than the class capacity b, and such that the sum of edge weights, for edges connecting nodes in the same class, is maximal. This...

1.2 Graph Partitioning 这个损失函数的设计思路是显而易见的,但该模型存在一个显著的问题。即,当图中节点数量较多,并且嵌入的维度也较大时,我们可能很难将整张图存在单个机器的内存中。 显然,为了解决这一问题,一个思路就是将图数据分布式的存储在集群中,后进行分布式的训练。比如,我们可以直接利用流行的图分割算...
self-organized systems. SI methods aim to imitate the behavior and apply it in finding solutions to hard computational problems. 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, fl...
This partial derivative has a natural interpretation as a difference between two expectations. The second term creates a matrix the same size as W, consisting of an observation and the hidden variable representation. The first term simply replaces the observation with a similar Wh factor, which ...
The task of multiple active contours is framed as a partitioning problem by assuming that image data are generated from a finite mixture model with unknown number of components. Then, the partitioning problem is solved within a divisive graph cut framework where multi-way minimum cuts for multiple...
1.3 The major steps in the VLSI circuit design flow, with a focus on the physical design steps: partitioning (Chap. 2), chip planning (Chap. 3), placement (Chap. 4), clock tree synthesis (Chap. 7), routing (Chaps. 5-6), and timing closure (Chap. 8). The steps of the VLSI ...
