Visualizing Dirichlet Distributions with Matplotlib

This post describes how I went about visualizing probability density functions of 3-dimensional Dirichlet distributions with matplotlib. If you're already familiar with the Dirichlet distribution, you might want to skip the next section.

Rolling Dice

To understand what the Dirichlet distribution describes, it is useful to consider how it ...

Anomalously Non-Anomalous Anomaly Detection Results

The RX Anomaly Detector

In image processing, anomaly detectors are algorithms used to detect image pixels that are sufficiently different than other pixels in the same image (or within a local neighborhood of the pixel being evaluated). The RX anomaly detector [1] represents each pixel in an image as a ...
