Unsupervised Learning using KMeans Clustering - Medium

Webk-means and hierarchical clustering remain popular. Only some clustering methods can handle arbitrary non-convex shapes including those supported in MATLAB: DBSCAN, hierarchical, and spectral clustering. Unsupervised learning (clustering) can also be used to compress data. WebJul 6, 2024 · k-means This algorithm is completely different. The k here denotes the number of assumed classes that exist in your dataset. For example if you have unlabeled pictures of red and green apples, you know that k = 2. The algorithm will then move the centroids (the average of the cluster distributions) to a stable solution. Here is an example: WebK-Means Clustering is an Unsupervised Learning algorithm, which groups the unlabeled dataset into different clusters.
