mlbench.simplex {mlbench} | R Documentation |
Corners of d-dimensional Simplex
Description
The created data are d
-dimensional spherical Gaussians with standard
deviation sd
and means at the corners of a
d
-dimensional simplex. The number of classes is d+1
.
Usage
mlbench.simplex(n = 800, d = 3, sides = 1, sd = 0.1, center=TRUE)
simplex(d, sides, center=TRUE)
Arguments
n |
number of patterns to create |
d |
dimensionality of simplex, default is 3 |
sides |
lengths of the sides of the simplex, default is to create a unit simplex |
sd |
standard deviation |
center |
If |
Value
Returns an object of class "mlbench.simplex"
with components
