tfp.math.clip_by_value_preserve_gradient
Clips values to a specified min and max while leaving gradient unaltered.
tfp . math . clip_by_value_preserve_gradient (
t , clip_value_min , clip_value_max , name = None
)
Like tf.clip_by_value
, this function returns a tensor of the same type and
shape as input t
but with values clamped to be no smaller than to
clip_value_min
and no larger than clip_value_max
. Unlike
tf.clip_by_value
, the gradient is unaffected by this op, i.e.,
tf . gradients ( tfp . math . clip_by_value_preserve_gradient ( x ), x )[ 0 ]
# ==> ones_like(x)
Note: clip_value_min
needs to be smaller or equal to clip_value_max
for
correct results.
Args
t
A Tensor
.
clip_value_min
A scalar Tensor
, or a Tensor
with the same shape
as t
. The minimum value to clip by.
clip_value_max
A scalar Tensor
, or a Tensor
with the same shape
as t
. The maximum value to clip by.
name
A name for the operation (optional).
Default value: 'clip_by_value_preserve_gradient'
.
Returns
clipped_t
A clipped Tensor
.
