Community Graph

This is Community Network Graph of facebook dataset generated using a coommunity detection algorithm developed by Thomas Aynaud. The dataset contains 4039 nodes and 88234 edges. Undirected graph used to represent friendship between person. Node degree may represent person charm. By measure nodes density, we want to reveal any social group or community.
As we can see, there were at least seven communities formed from facebook dataset. All communities defined by their density. Furthermore, some communities tend to make isolation from major cluster. Some isolated communities may only communicate to major cluster through only one person. We call this kind of person as broker.

Anomaly Detection

Using Gaussian Distribution Estimation to detect anomalous behavior in server computers. All normal server behaviors placed in the middle of contours, while all abnormal server behaviors placed far from the middle of contours.
A dataset contains thousand of server behavior and consists eleven features. But in this case, I only used two features: throughput (mb/s) and latency (ms). Intuitively, we expect that data contains so many normal server behaviors, but small abnormal server behaviors. So, based on that estimation, I used gaussian distribution model all servers behaviors. An image above visualize Gaussian distribution contours.
