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.

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
