What is clustering
- unsupervised classification
- Group data objects based only on information found in data that describes the objects and their relationships.
- User-specified number of clusters(K).
- Euclidean distance approach used between data objects.
k-means Clustering Algorithm
- Select K points as initial centroids
- repeat
- Form K clusters by assigning each point to its closest centroid
- recompute the centroid of each cluster
- until Centroids do not change
