Database Reference
In-Depth Information
Glass : The study of classification of types of glass was motivated by
criminological investigation. At the scene of the crime, the glass left can be used
as evidence if it is correctly identified.
Iris : The data set contains three classes of 50 instances each, where each class
refers to a type of iris plant. One class is linearly separable from the other two; the
latter are NOT linearly separable from each other.
LED24Dig : This simple domain contains 24 Boolean attributes and 10 concepts,
the set of decimal digits. Recall that LED displays contain 24 light-emitting diodes
-- hence the reason for seven attributes. The problem would be easy if not for the
introduction of noise.
LED7Dig : This simple domain contains seven Boolean attributes and 10
concepts, the set of decimal digits. Recall that LED displays contain seven light-
emitting diodes -- hence the reason for seven attributes. The problem would be
easy if not for the introduction of noise.
Lymphography : This lymphography domain was obtained from the University
Medical Centre, Institute of Oncology, Ljubljana, Yugoslavia.
Monk : The MONK's problem was the basis of a first international comparison
of learning algorithms. The result of this comparison is summarized in “the
MONK's problems.”
Pima : The diagnostic, binary-valued variable investigated is whether the patient
shows signs of diabetes according to World Health Organization criteria (i.e., if
the two-hour postload plasma glucose was at least 200 mg/dl at any survey
examination or if found during routine medical care). The population lives near
Phoenix, Arizona, USA.
Wine : These data are the results of a chemical analysis of wines grown in the
same region in Italy but derived from three different cultivars. The analysis
determined the quantities of 13 constituents found in each of the three types of
wines.
Wisconsin : This breast cancer database was obtained from the University of
Wisconsin Hospitals, Madison, from Dr. William H. Wolberg.
