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, -5.0, 2.6, 0.8, 10.0], 0.25);
Additional Methods#
Fit a Blob generator to the samples in a dataset.
public static simulate(Dataset $dataset) : self
Return the center coordinates of the Blob.
public center() : array
