tfa.activations.hardshrink

Hard shrink function.

Computes hard shrink function:

\[ \mathrm{hardshrink}(x) = \begin{cases} x & \text{if } x < \text{lower} \\ x & \text{if } x > \text{upper} \\ 0 & \text{otherwise} \end{cases}. \]

Usage:

x = tf.constant([1.0, 0.0, 1.0])
tfa.activations.hardshrink(x)
<tf.Tensor: shape=(3,), dtype=float32, numpy=array([1., 0., 1.], dtype=float32)>

x A Tensor. Must be one of the following types: bfloat16, float16, float32, float64.
lower float, lower bound for setting values to zeros.
upper float, upper bound for setting values to zeros.

A Tensor. Has the same type as x.
