(Python, R, C++) Explainable outlier/anomaly detection through decision tree conditioning

Arduino library for identifying outliers with a Hampel filter

This is an open source library that can be used to autofocus telescopes. It uses a novel algorithm based on robust statistics. For a preprint, see https://arxiv.org/abs/2201.12466 .The library is currently used in Astro Photography tool (APT) https://www.astrophotography.app/
