Tanagra is a free suite of machine learning software for research and academic purposes developed by Ricco Rakotomalala at the Lumière University Lyon 2, France.[1] Tanagra supports several standard data mining tasks such as: Visualization, Descriptive statistics, Instance selection, feature selection, feature construction, regression, factor analysis, clustering, classification and association rule learning.
Tanagra is an academic project. It is widely used in the French speaking Universities.[2] Tanagra is frequently used in real studies[3][4] and in the software comparison papers.[5][6]
History
The development of Tanagra was started in June 2003. The first version is distributed in December 2003. Tanagra is the successor of Sipina, another free data mining tool which is intended only for the supervised learning tasks (classification), especially an interactive and visual construction of decision trees. Sipina is still available online and is maintained. Tanagra is an "open source project" as every researcher can access to the source code, and add his own algorithms, as far as he agrees and conforms to the software distribution license.
The main purpose of Tanagra project is to give researchers and students a user-friendly data mining software, conforming to the present norms of the software development in this domain (especially in the design of its GUI and the way to use it), and allowing to analyze either real or synthetic data.
From 2006, Ricco Rakotomalala made an important documentation effort. A large number of tutorials are published on a dedicated website. They describe the statistical and machine learning methods and their implementation with Tanagra on real case studies. The use of the other free data mining tools on the same problems is also widely described. The comparison of the tools enables to the readers to understand the possible differences in the presenting of results.
Description
Tanagra works as the current data mining tools. The user can design visually a data mining process in a diagram. Each node is a statistical or machine learning technique, the connection between two nodes represents the data transfer. But unlike of the majority of the tools which are based on the workflow paradigm, Tanagra is very simplified. The treatments are represented in a tree diagram. The results are displayed in a HTML format. So it is easy to export the outputs in order to visualize the results in a browser. It is also possible to copy the result tables to a spreadsheet.
Tanagra makes a good compromise between the statistical approaches (e.g. parametric and nonparametric statistical tests), the multivariate analysis methods (e.g. factor analysis, correspondence analysis, cluster analysis, regression) and the machine learning techniques (e.g. neural network, support vector machine, decision trees, random forest).
