Parameters:

scale (Array | ndarray | bool | number | bool | int | float | complex | Quantity) – Scaling factor (default: 1.0).

Examples

>>> import numpy as np
>>> from braintools.init import XavierNormal
>>>
>>> init = XavierNormal()
>>> rng = np.random.default_rng(0)
>>> weights = init((100, 50), rng=rng)
