Python _softplus_grad Examples

Example #1

def _SoftplusGradGrad(op, grad):
    # Let:
    #   y = tf.nn.softplus(x)
    #   dx = gen_nn_ops._softplus_grad(dy, x) = dy / (1 + exp(-x))
    # This op computes (ddy, d2x) from op.inputs == [dy, x] and grad == ddx.
    dy, x = op.inputs
    with ops.control_dependencies([grad.op]):
        ddy = gen_nn_ops._softplus_grad(grad, x)  # pylint: disable=protected-access
        d2x = grad * dy / (math_ops.exp(-x) + 2.0 + math_ops.exp(x))
        return (ddy, d2x)
