The Machine Learning “Advent Calendar” Day 10: DBSCAN in Excel
https://towardsdatascience.com/the-machine-learning-advent-calendar-day-10-dbscan-in-excel/
Published: December 10, 2025 16:30
DBSCAN shows how far we can go with a very simple idea: count how many neighbors live close to each point. It finds clusters and marks anomalies without any probabilistic model, and it works beautifully in Excel. But because it relies on one fixed radius,…

The Machine Learning “Advent Calendar” Day 8: Isolation Forest in Excel
https://towardsdatascience.com/the-machine-learning-advent-calendar-day-8-isolation-forest-in-excel/
Published: December 8, 2025 18:26
Isolation Forest may look technical, but its idea is simple: isolate points using random splits. If a point is isolated quickly, it is an anomaly; if it takes many splits, it is normal. Using the tiny dataset 1, 2, 3, 9, we can see the logic clearly. We…
