WebMar 6, 2024 · K-means is a very simple clustering algorithm used in machine learning. Clustering is an unsupervised learning task. Learning is unsupervised when it requires … WebFeb 5, 2024 · So, we first learn the class labels from the data and then train a classifier to discriminate between the classes discovered while clustering. For example, K-Means finds these three clusters (classes) and centroids in the above data: Then, we could train a neural network to differentiate between the three classes. 4.
