Zeros¶
Constant initializer which always returns zeros.
Examples¶
from river import optim
init = optim.initializers.Zeros()
init(shape=1)
0.0
init(shape=2)
array([0., 0.])
Methods¶
call
Returns a fresh set of weights.
The return type is shape-dependent (a scalar when shape == 1, otherwise an array), and these values are routinely used as collections.defaultdict factories elsewhere, so the return is intentionally left dynamic.
Parameters
- shape —
int— defaults to1
