Cahit Arf V1.0 - A Data Extraction Utility for Weka

Cahit Arf by Prime Components is an open source (LGPL licensed) utility for WEKA machine learning library which simplifies data extraction from relational databases and ARFF file preparation. Refer to the User's Guide for more technical details and installation.

You can get more information about "Attribute-Relation File Format (ARFF)" from WEKA project site or a local copy of ARFF specification.

What does 'Cahit Arf' mean?

Cahit Arf is a famous Turkish mathematician (1910-1997).

Professor Ikeda says :

"To every problem, he has his own idea of approach. The characteristic of his approach is thoroughness; he always seeks invariants, and prefers explicit constructions rather than combination of existing theories. Once he determines his approach, he energetically tackles the problem and never gives up until he achieves his aim. If one studies Cahit Arf's works, which are full of originality and painstaking computations, one will surely wonder where Arf gets his inspirations, and how he gets insight into most complicated computations."

(Ikeda, PhD)

TO DO List

Improvement ideas to be implemented in the next releases of Cahit Arf :

• Parameterized 'select' statements : Building queries with run time parameter(s) would be useful particularly for scheduled batch operations.
• Better API documentation : Source code documented poorly and, hence, API documentation has not generated yet.
• Internationalization (I18n) : Although Cahit Arf is a very small utility and contains very few UI elements and messages, I18n capability is considered carefully during coding process. If you wish Cahit Arf to support your language, translate 'messages.properties' file in the lib directory and send it to me, or join the development group.

We will appreciate if you send your wish lists and opinions to the developer, or Join project forums at SourceForge.
