Webb20 jan. 2024 · Clustering is a technique of grouping data together with similar characteristics in order to identify groups. This can be useful for data analysis, recommender systems, search engines, spam filters, and image segmentation, just to name a few. A centroid is a data point at the center of a cluster. K-Means is a clustering … Webb21 sep. 2024 · Clustering is an unsupervised machine learning task. You might also hear this referred to as cluster analysis because of the way this method works. Using a clustering algorithm means you're going to give the algorithm a lot of input data with no labels and let it find any groupings in the data it can. Those groupings are called clusters.

"WebbAffinity Propagation is a newer clustering algorithm that uses a graph based approach to let points ‘vote’ on their preferred ‘exemplar’. The end result is a set of cluster ‘exemplars’ from which we derive clusters by essentially doing what K-Means does and assigning each point to the cluster of it’s nearest exemplar.
