In this paper, we propose a graph-based label propagation algorithm (GLPA) to detect communities incorporating the node similarity and connectivity information during the propagation of the labels. First, we define node similarity between adjacent nodes, and change each node's label to that of its...

实践中,labeled数据是昂贵,很难获得的,但unlabeled数据就不是了,写个脚本在网上爬就可以了,因此如果能充分利用大量的unlabeled数据来辅助提升我们的模型学习,这个价值就非常大。半监督学习算法有很多,下面我们介绍最简单的标签传播算法(label propagation) 标签传播算法(label propagation) 标签传播算法Label Propagation Al...
It runs the algorithm over the whole graph, but only queries the component ID of one node: CALL neptune.algo.labelPropagation( ["101"], { edgeLabels: ["route"], maxIterations: 10, vertexLabel: "airport", vertexWeightProperty: "runways", vertexWeightType: "int", edgeWeightProperty: "...

Label propagation works by creating a graph of the data points, with weights placed on the edge equal to the following: 标签传播算法运行是通过生成数据点的图形,通过以下公式来定位距离的边界。 The algorithm then works by labeled data points propagating their labels to the unlabeled data.This propaga...
A popular approach to semi-supervised learning is to create a graph that connects examples in the training dataset and propagate known labels through the edges of the graph to label unlabeled examples. An example of this approach to semi-supervised learning is the label propagation algorithm for ...
1.A computer-implemented method when executed by one or more processors causes the one or more processors to perform operations comprising:obtaining, during an iteration of a label propagation algorithm, a set of vertices from a graph representing relationships among data items;obtaining a first labe...
