Is clustering supervised or unsupervised? How do you classify it?

WebAug 5, 2024 · In supervised classification, the distance measure is the class of the target variable. In unsupervised or semi-supervised learning, the clustering is done based on a distance metric (e.g Euclidean). If a small sample is labeled, all the (unlabeled) samples in a node are assigned the class of the majority of the labeled samples. WebUnsupervised clustering is a learning framework using a specific object functions, for example a function that minimizes the distances inside a cluster to keep the cluster tight. …
