Degree Correlation
Updated on 2022-09-15 GMT+08:00
Overview
The Degree Correlation algorithm calculates the Pearson correlation coefficient between the source vertex degree and the target vertex degree of each edge. It is used to indicate whether the high-degree nodes are connected to other high-degree nodes in a graph.
Application Scenarios
This algorithm is often used to measure the structure features of a graph.
Parameter Description
None
Example
Run the algorithm to calculate the degree correlation of a graph. The JSON result is displayed in the query result area.
