tf.compat.v1.keras.activations.hard_sigmoid
tf.keras.activations.hard_sigmoid(
x
)
Faster to compute than sigmoid activation.
For example:
a = tf.constant([-3.0,-1.0, 0.0,1.0,3.0], dtype = tf.float32)
b = tf.keras.activations.hard_sigmoid(a)
b.numpy()
array([0. , 0.3, 0.5, 0.7, 1. ], dtype=float32)
Arguments |
|---|
x
|
Input tensor.
|
Returns |
|---|
The hard sigmoid activation:
0 if x < -2.51 if x > 2.50.2 * x + 0.5 if -2.5 <= x <= 2.5.
