Lecture Notes for Chapter 7 Introduction to Data Mining
Hierarchical clustering algorithms typically have local objectives Partitional algorithms typically have global objectives – A variation of the global objective function approach is to fit the data to a parameterized model Parameters for the model are determined from the data
BASICS of CLUSTER ANALYSIS - SBU
Introduction to Cluster Analysis • The process of grouping a set of physical or abstract objects into classes of similar objects is called clustering • A cluster is a collection of data objects that are similar to one another within the same cluster and are dissimilar to the objects in other clusters
CS6220: Data Mining Techniques - University of California
Summary •Cluster analysis groups objects based on their similarity and has wide applications •Measure of similarity can be computed for various types of data •Clustering algorithms can be categorized into partitioning methods hierarchical methods density-based methods grid-based methods and others
Cluster Analysis: Basic Concepts and Algorithms
Basic algorithm is straightforward 1 Compute the proximity matrix 2 Let each data point be a cluster 3 Repeat 4 Merge the two closest clusters 5 Update the proximity matrix 6 Until only a single cluster remains Key operation is the computation of the proximity of two clusters Different approaches to defining the distance
What is clustered analysis?
- Cluster Analysis: Basic Concepts and Algorithms Cluster analysisdividesdata into groups (clusters) that aremeaningful, useful, orboth. Ifmeaningfulgroupsarethegoal, thentheclustersshouldcapturethe natural structure of the data. In some cases, however, cluster analysis is only a useful starting point for other purposes, such as data summarization.
What is Cluster Analysis Chapter 8 in DBMS?
- 492 Chapter 8 Cluster Analysis: Basic Concepts and Algorithms or unnested, or in more traditional terminology, hierarchical or partitional. A partitional clustering is simply a division of the set of data objects into non-overlapping subsets (clusters) such that each data object is in exactly one subset.
What motivates clustering algorithms?
- A key motivation is that almost every clustering algorithm will ?nd clusters in a data set, even if that data set has no natural cluster structure. For instance, consider Figure 8.26, which shows the result of clustering 100 points that are randomly (uniformly) distributed on the unit square.
What is SSE in cluster analysis?
- SSE = K i=1 x?Ci (c i?x)2(8.4) 514 Chapter 8 Cluster Analysis: Basic Concepts and Algorithms Here, C iis the ithcluster, x is a point in C i, and c iis the mean of the ith cluster.
