Hard sigmoid activation.
A faster approximation of the sigmoid activation.
Defined as:
if x < -2.5: return 0
if x > 2.5: return 1
if -2.5 <= x <= 2.5: return 0.2 * x + 0.5
For example:
Operand<TFloat32> input = tf.constant(
new float[] {-3.0f,-1.0f, 0.0f,1.0f,3.0f});
HardSigmoid<TFloat32> hardSigmoid = new HardSigmoid<>(tf);
Operand<TFloat32> result = hardSigmoid.call(input);
// result is [0.f , 0.3f, 0.5f, 0.7f, 1.f]
