tf.clip_by_average_norm(t, clip_norm, name=None)
See the guide: Training > Gradient Clipping
Clips tensor values to a maximum average L2-norm.
Given a tensor t
, and a maximum clip value clip_norm
, this operation normalizes t
so that its average L2-norm is less than or equal to clip_norm
. Specifically, if the average L2-norm is already less than or equal to clip_norm
, then t
is not modified. If the average L2-norm is greater than clip_norm
, then this operation returns a tensor of the same type and shape as t
with its values set to:
t * clip_norm / l2norm_avg(t)
In this case, the average L2-norm of the output tensor is clip_norm
.
This operation is typically used to clip gradients before applying them with an optimizer.
