The prior chapter provided us with an introduction to clustering techniques and the use of one such clustering technique, Gaussian Mixture Models. Over the course of this chapter, we will implement a separate technique for multivariate clustering: Connectivity-Based Outlier Factor.
Distance or Density?
There are two key approaches to outlier detection: distance-based approaches and density-based approaches. For univariate anomaly detection, we generally focused on distance-based approaches. As Mehrotra ...
