tf.keras.ops.nn.hard_tanh

tf.keras.ops.hard_tanh(
    x
)

It is defined as:

f(x) = -1 for x < -1, f(x) = x for -1 <= x <= 1, f(x) = 1 for x > 1.

Args
x	Input tensor.

Returns
Output tensor of same shape as x where values are clamped between -1 and 1.

Example:

x = np.array([-2., -1., 0., 1., 2.])
x_hard_tanh = keras.ops.hard_tanh(x)
print(x_hard_tanh)
array([-1. -1.  0.  1.  1.], shape=(5,), dtype=float64)
