Machine learning for anomaly detection: Elliptic Envelope

Bite-sized data science

--

Welcome back to anomaly detection; this is 6th in a series of “bite-sized” data science focusing on outlier detection. Today I am writing about a machine learning algorithm called EllipticEnvelope , which is yet another tool in data scientists’ toolbox for fraud/anomaly/outlier detection.

In case you have missed my previous articles or you are interested in learning more about the topic, find the links below:

Elliptical Envelope

So what is elliptic envelope and what’s the intuition behind the algorithm?

If you have taken geometry classes you are probably familiar with ellipse — a geometric configuration that takes an oval shape on a two-dimensional plane.

Conceptual diagram of the elliptical envelope

The green area in the above diagram is an ellipse. So the algorithm — Elliptical Envelope— creates an imaginary elliptical area…
