Select data set
In the field Data set (URL):, you may give an URL to the data
set, an ARFF-file
Just insert the URL in to the field, e.g.
http://www.hakank.org/weka/zoo2.arff
Or maybe just select some of the sample data set in the list
(Select data set:).
The ARFF file format is a specific format for defining the data set. See
the information here about the sample
data sets I have provided.
