Research Tools in Data Mining
Free Softwares
Many free soft wares are available in theMarket. Some of them are Free.
Major Software companies have also brought out Data Mining packages such as IBM, Oracle and Microsoft.
Open Source Data mining Tool - WEKA
Weka is an open source data mining tool developed in Java.
Weka was developed at the University of Waikato in New Zealand. http://www.cs.waikato.ac.nz/ml/weka/
It is used for research, education, and applications.
It can be run on Windows, Linux and Mac.
Weka Tools/Functions
Tools (or functions) in Weka include:
Data preprocessing (e.g., Data Filters),
Classification (e.g., BayesNet, KNN, C4.5 Decision Tree, Neural Networks, SVM),
Regression (e.g., Linear Regression, Isotonic Regression, SVM for Regression),
Clustering (e.g., Simple K-means, Expectation Maximization (EM)),
Association Rules (e.g., Apriori Algorithm, Predictive Accuracy, Confirmation Guided),
Feature Selection (e.g., CFS Subset Evaluation, Information Gain, Chi-squared Statistic), and
Visualization (e.g., View different two-dimensional plots of the data).
