The inputs of the cassini problem are uniformly distributed on a 2-dimensional space within 3 structures. The 2 external structures (classes) are banana-shaped structures and in between them, the middle structure (class) is a circle.

Usage

mlbench.cassini(n, relsize=c(2,2,1))

Value

Returns an object of class "mlbench.cassini" with components

x

input values

classes

vector of length n with target classes

Arguments

n

number of patterns to create

relsize

relative size of the classes (vector of length 3)
