Dear Ashen I know you have programmed correctly, but here too it is better to show that if (ri > di ) for all i=1..k => Anomalous where k is the number of clusters di is the distance between the point under consideration and the cluster centre i and ri is the percentile radius of cluster i

Variables of the above diagram. - Cc1, Cc2, Cc3 - Cluster centers - r1 - ith percentile distance of distances of all the points of cluster 1 to their cluster center (Cc1) (this is considered as the boundary of cluster 1) - d1 - distance between

Thanks for the suggestion! This diagram shows how the algorithm detect anomaly behaviors. As in the diagram when we do the K means clustering there will be set of clusters of normal data and some deviated points which behave as anomalies. since we consider a percentile distance to identify cluster

Thanks Ashen! Few diagrams will help readers to understand the algorithm better. On Wed, Sep 23, 2015 at 6:03 PM, Ashen Weerathunga wrote: > Hi all, > > I am currently doing the integration of Anomaly detection feature to the > WSO2 ML. There are some anomaly/fraud detection features already > i

[Architecture] [ML] Anomaly Detection Feature for WSO2 ML

2015-09-23 Thread Ashen Weerathunga
Hi all, I am currently doing the integration of Anomaly detection feature to the WSO2 ML. There are some anomaly/fraud detection features already implemented in CEP/DAS using different approaches. But this will be done using a machine learning approach which is K means clustering. Basically I have
