[source] # 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 ```php 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. ```php public static simulate(Dataset $dataset) : self ``` Return the center coordinates of the Blob. ```php public center() : array ```
