What is a centroid?
The center of a cluster as determined by a k-means or k-median algorithm.
centroid explained in plain English
The center of a cluster as determined by a k-means or k-median algorithm. For example, if k is 3, then the k-means or k-median algorithm finds 3 centroids. See Clustering algorithms in the Clustering course for more information.
Example
Practitioners refer to centroid when building, training, or evaluating machine learning systems. It appears in research papers, product documentation, and technical discussions about AI capabilities and limitations.
