Understanding K-means Clustering in Machine Learning

WebIn k-means clustering, we are given a set of n data points in d-dimensional space R/sup d/ and an integer k and the problem is to determine a set of k points in Rd, called centers, so as to minimize the mean squared distance from each data point to its nearest center. A popular heuristic for k-means clustering is Lloyd's (1982) algorithm. WebExplore and run machine learning code with Kaggle Notebooks Using data from Wholesale customers Data Set.

"WebJan 2, 2024 · As the name suggests, clustering is the act of grouping data that shares similar characteristics. In machine learning, clustering is used when there are no pre-specified labels of data available, i.e. we don’t know what kind of groupings to create. The goal is to group together data into similar classes such that: " - Data set for k means clustering
