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. Web• The number of clusters can be known from context. ∗E.g., clustering genetic profiles from a group of cells that is known to contain a certain number of cell types • Visualising the data (e.g., using multidimensional reduction, next week) can help to estimate the number of clusters • Another strategy is to try a few plausible values ...
