Soft Shrink activation function.
tf.keras.ops.soft_shrink(
x, threshold=0.5
)
It is defined as
f(x) = x - threshold if x > threshold,
f(x) = x + threshold if x < -threshold,
f(x) = 0 otherwise.
Args |
|---|
x
|
Input tensor.
|
threshold
|
Threshold value. Defaults to 0.5.
|
Returns |
|---|
A tensor with the same shape as x.

Example:
x = np.array([-1.0, 0.0, 1.0])
x_soft_shrink = keras.ops.soft_shrink(x)
print(x_soft_shrink)
array([-0.5 0. 0.5], shape=(3,), dtype=float64)
