Datasets

This is a collection of datasets used in some of my feature selection experimentation. Many of these datasets come from the UCI Machine Learning Repository. The decision attribute is always the final column in the dataset.

Crisp Datasets
These datasets contain discrete values only:

Real-valued Datasets
These datasets contain real-valued attributes:

Abalone
Arrhythmia
Caco
Fruit
FUZZIEEE example
Glass
Ionosphere
Iris
Isolet
Vehicle
Water Treatment
Waveform
Website classification

Fuzzification files

Note that these have not been optimized. For use in fuzzy-rough
attribute reduction (FRAR):

Abalone
Arrhythmia
Caco

FUZZIEEE example
Glass
Ionosphere
Iris
Isolet

Wine

A readme file containing some more description can be found here.

An example dataset and fuzzification for FRAR can be found below. The decision
attribute is fuzzy.
