Anomaly detection techniques are widely used in a various type of applications. The authors explored proximity graphs for anomaly detection and the page rank algorithm. They used a different page rank algorithm at peak in proximity graph collection of data points indicated by vertices, gives results a score quantifying the extent to which each data point is anomalous. In this way they requires first forming a density calculating using the training data, it was high calculative intensive for sets of high-dimensional data.
