View source: R/mlbench-class.R

Description

The inputs of the circle problem are uniformly distributed on the d-dimensional cube with corners {+-1}. This is a 2-class problem: The first class is a d-dimensional ball in the middle of the cube, the remainder forms the second class. The size of the ball is chosen such that both classes have equal prior probability 0.5.
