optax.scale_by_sm3(b1: jax.typing.ArrayLike = 0.9, b2: jax.typing.ArrayLike = 1.0, eps: jax.typing.ArrayLike = 1e-08) → optax.GradientTransformation[source]#

Scale updates by sm3.

See optax.sm3() for more details.

Parameters:

  • b1 – Decay rate for the exponentially weighted average of grads.

  • b2 – Decay rate for the exponentially weighted average of squared grads.

  • eps – Term added to the denominator to improve numerical stability.

Returns:

A optax.GradientTransformation object.
