Webstanford-cs221.github.io WebSep 11, 2024 · Kmeans algorithm is an iterative algorithm that tries to partition the dataset into K pre-defined distinct non-overlapping subgroups (clusters) where each data point belongs to only one group. It tries to make the inter-cluster data points as similar as possible while also keeping the clusters as different (far) as possible.

WebK -means clustering is one of the most commonly used clustering algorithms for partitioning observations into a set of k k groups (i.e. k k clusters), where k k is pre-specified by the analyst. k -means, like other clustering algorithms, tries to classify observations into mutually exclusive groups (or clusters), such that observations within the …
