Rarff is a Ruby library for dealing with Attribute-Relation File Format (ARFF) files. ARFF files are used to specify data sets for data mining and machine learning.

- Spaces or quotes in nominal types
- Commas in quoted attributes or in nominal types
- Add error checking/validation
- Creation of sparse ARFF files
- Missing values - '?'
- Dates - do some work to create, translate, and interpret date format strings.
Weka is "a collection of machine learning algorithms for data mining tasks." (http://www.cs.waikato.ac.nz/ml/weka/) Weka accompanies the following book:
Ian H. Witten and Eibe Frank (2005) "Data Mining: Practical machine learning tools and techniques", 2nd Edition, Morgan Kaufmann, San Francisco, 2005.
ARFF files are similar to CSV files, but are strongly-typed, have a pre-defined set of data types, and include a sparse representation.
