How to perform anomaly detection with LOF

An introduction to performing outlier detection with the Native Outlier Issue (LOF) algorithm.

Anomaly detection, though helpful, is a subject that usually will get skipped in machine studying lessons. There are lots of purposes of anomaly detection, particularly in areas reminiscent of fraud detection and system monitoring.

If you happen to’ve adopted my weblog for a while, you’ll do not forget that I beforehand wrote an article about utilizing Isolation Forests for anomaly detection.

Other than Isolation Forests, there’s additionally one other anomaly detection often known as the Native Outlier Issue (LOF) that additionally performs effectively in apply. On this article, I’ll briefly go over the LOF algorithm and in addition reveal how you should use this algorithm for anomaly detection in Python.

The LOF algorithm is an unsupervised algorithm for anomaly detection. It borrows ideas from the…
