WebThe algorithm assigns each observation to a cluster and also finds the centroid of each cluster. The K-means Algorithm: Selects K centroids (K rows chosen at random). Then, we have to assign each data point to its closest centroid. Moreover, it recalculates the centroids as the average of all data points in a cluster. WebMay 9, 2024 · Since HAC is a clustering algorithm, it sits under the Unsupervised branch of Machine Learning. Unsupervised techniques, in particular clustering, are often used for segmentation analysis or as a starting point in more complex projects that require an understanding of similarities between data points (e.g., customers, products, behaviors).
