Description

This section describes main characteristics of the 04clover5z-600-5-50-BI data set and its attributes:

General information

Minority Class with Shape as Clover (examples = 600, disturbance ratio = 50%, IR = 5) data set
Type	Imbalanced	Origin	Real world
Features	2	(Real / Integer / Nominal)	(2 / 0 / 0)
Instances	600	IR	5
% Positive instances	16.67	% Negative instances	83.33
Missing values?	No

Attribute description

Attribute	Domain
dim1	[-573.0,533.0]
dim2	[-412.0,413.0]
class	{0, 1}

Additional information

This is an artificial data set with 2 classes (the minority and the majority class) and 600 examples randomly and uniformly distributed in the two-dimensional space (both attributes were real-valued). The minority class resembles a flower with elliptic petals. The borders of sub-regions in the minority class are disturbed increasing the ratio of borderline examples from the minority class subregions (the disturbance ratio) in 50%.
