– A cluster is a set of objects such that an object in a cluster is closer (more similar) to the center of a cluster, than to the center of any other cluster –The center of a cluster is called centroid –Each point is assigned to the cluster with the closest centroid –The number of clusters usually should be specified

• Clustering is a process of partitioning a set of data (or objects) into a set of meaningful sub-classes, called clusters. • Help users understand the natural grouping or structure in a data set. • Clustering: unsupervised classification: no predefined classes. • Used either as a stand-alone tool to get insight into data

Examples for extra credit We are trying something new. At the start of class, a student volunteer can give a very short presentation (= 4 minutes!), showing a cool example of something we learned in class.This can be an example you found in the news or in the literature, or something you thought of yourself---whatever it is, you will explain it to us clearly.

In this paper, we make a multiview extension of the spectral rotation technique raised in single view spectral clustering research. Since spectral rotation is closely related to the Procrustes Analysis for points matching, we point out that classical Procrustes Average approach can be used for multiview clustering. Besides, we show that direct applying Procrustes Average (PA) in multiview ...

Data does not always come in a nice tabular form. It can also be a collection of text, audio recordings, video materials or even images. However, computers can only work with numbers, so for any data mining, we need to transform such unstructured data into a vector representation.
