DATA WAREHOUSING AND MINIG LECTURE NOTES-- Clustering tools


Clustering tools
 
Clustering tools are beneficial when you want to find structure or clusters in data, but dont necessarily have a target variable. Clustering is used often in marketing research applications as well as many others. This session looks at the clustering tools available in STATISTICA Data Miner and demonstrates the K-means clustering tool as well as the Kohonen network clustering tool.

Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes.

List of clustering tools:

1.      CLUTO

2.      Model based clustering

3.      Open source clustering software

4.      Online software for clustering
