Blob#

A normally distributed (Gaussian) n-dimensional blob of samples centered at a given vector. The standard deviation can be set for the whole blob or for each feature column independently. When a global standard deviation is used, the resulting blob will be isotropic and will converge asymptotically to a sphere.

Data Types: Continuous

Label Type: Unlabeled

Parameters#

# Name Default Type Description
1 center [0, 0] array An array containing the coordinates of the center of the blob.
2 stddev 1.0 float or array Either the global standard deviation or an array with the standard deviation on a per feature column basis.

Example#

use Rubix\ML\Datasets\Generators\Blob;

$generator = new Blob([-1.2, -5., 2.6, 0.8, 10.], 0.25);

Additional Methods#

This generator does not have any additional methods.
