Meta-Data was used in order to give advice about which classification method is appropriate for a particular dataset. This work is described in: -"Machine Learning, Neural and Statistical Learning" Eds. D.Michie,D.J.Spiegelhalter and C.Taylor Ellis Horwood-1994 - "Characterizing the Applicability of Classification Algorithms Using Meta-Level Learning", P. Brazdil, J.Gama and B.Henery: in Proc. of Machine Learning - ECML-94, ed. F.Bergadano and L.de Raedt,LNAI Vol.784 Springer-Verlag. -"Characterization of Classification Algorithms" J.Gama, P.Brazdil in Proc. of EPIA 95, LNAI Vol.990 Springer-Verlag, 1995Relevant Information:n This DataSet is about the results of Statlog project. The project performed a comparative study between Statistical, Neural and Symbolic learning algorithms.
Project StatLog (Esprit Project 5170) was concerned with comparative studies of different machine learning, neural and statistical classification algorithms. About 20 different algorithms were evaluated on more than 20 different datasets. The tests carried out under project produced many interesting results.

Number of Attributes: 22 (including an Id#) plus the class attribute -- all but two attributes are continuously valued
Attribute Information:
DS_Name categorical Name of DataSet
T continuous Number of examples in test set
N continuous Number of examples
p continuous Number of attributes
k continuous Number of classes
Bin continuous Number of binary Attributes
Cost continuous Cost (1=yes,0=no)
SDratio continuous Standard deviation ratio
correl continuous Mean correlation between attributes
cancor1 continuous First canonical correlation
cancor2 continuous Second canonical correlation
fract1 continuous First eigenvalue
fract2 continuous Second eigenvalue
skewness continuous Mean of |E(X-Mean)|^3/STD^3
kurtosis continuous Mean of |E(X-Mean)|^4/STD^4
Hc continuous Mean entropy of attributes
Hx continuous Entropy of classes
MCx continuous Mean mutual entropy of class and attributes
EnAtr continuous Equivalent number of attributes
NSRatio continuous Noise-signal ratio
Alg_Name categorical Name of Algorithm
Norm_error continuous Normalized Error (continuous class)
Missing Attribute Values:
Note that fract2 and cancor2 only apply to datasets with more than 2 classes. When they appear as '?' this means a don't care value.
