Softsign

सॉफ्टसाइन सक्रियण फ़ंक्शन, softsign(x) = x / (abs(x) + 1)

उदाहरण उपयोग:

     Operand<TFloat32> input = tf.constant(
              new float[] {-1.0f, 0.0f, 1.0f});
     Softsign<TFloat32> softsign = new Softsign<>(tf);
     Operand<TFloat32> result = softsign.call(input);
     // result is [-0.5f, 0.f, 0.5f]
