can anyone help me? How we can use page rank algorithm for detection of anomalies ?
Maybe this books will give an answer on your problems: https://www.hindawi.com/journals/ijta/2019/8612021/
A good way to look for anomalies is to run page rank and then examine the nodes that are "outliers" -- meaning anything more than 3 standard deviations away from the mean, or even just the highest percentiles. If you'd like to get a sense of the distribution of your data, you can run pagerank in the
.stats mode with
CALL gds.pageRank.stats -- see the docs for more details - https://neo4j.com/docs/graph-data-science/current/algorithms/page-rank/#algorithms-pagerank-examples-stats
