Unsupervised clustering.

Clustering. Clustering is the assignment of objects to homogeneous groups (called clusters) while making sure that objects in different groups are not similar. Clustering is considered an unsupervised task as it aims to describe the hidden structure of the objects. Each object is described by a set of characters called features.9.1 Introduction. After learing about dimensionality reduction and PCA, in this chapter we will focus on clustering. The goal of clustering algorithms is to find homogeneous subgroups within the data; the grouping is based on similiarities (or distance) between observations. The result of a clustering algorithm is to group the observations ...Time Series Clustering is an unsupervised data mining technique for organizing data points into groups based on their similarity. The objective is to maximize data similarity within clusters and minimize it across clusters. The project has 2 parts — temporal clustering and spatial clustering.The k-means clustering method is an unsupervised machine learning technique used to identify clusters of data objects in a dataset. There are many different types of clustering methods, but k-means is one of the …
