OPTICS Clustering algorithm. How to get the best epsilon

WebSep 21, 2024 · K-means clustering is the most commonly used clustering algorithm. It's a centroid-based algorithm and the simplest unsupervised learning algorithm. This algorithm tries to minimize the variance of data points within a cluster. It's also how most people are introduced to unsupervised machine learning. WebWe saw that OPTICS works by ordering based on reachability distance while expanding the clusters at the same time. The output of the OPTICS algorithm is therefore an ordered list … WebSo there is a very powerful clustering algorithm called OPTICS which I wanted to utilize for my project, but I just couldn't find a proper and fast enough Python implementation I could use.
