ott.core.icnn.ICNN.init_fn#

ICNN.init_fn(dtype=<class 'jax.numpy.float64'>)#

Builds an initializer that returns real normally-distributed random arrays.

Parameters
  • stddev (Any) – optional; the standard deviation of the distribution.

  • dtype (Any) – optional; the initializer’s default dtype.

Return type

Initializer

Returns

An initializer that returns arrays whose values are normally distributed with mean 0 and standard deviation stddev.
