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);
