WebFeb 5, 2024 · The purpose of cluster analysis (also known as classification) is to construct groups (or classes or clusters) while ensuring the following property: within a group the observations must be as similar … 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.
