dragon.vm.tensorflow.keras.activations.selu(
  x,
  **kwargs
)[source]¶

Apply the scaled exponential linear unit to input. [Klambauer et.al, 2017].

\[\text{SELU}(x) = 1.0507 * \begin{cases} x, & \text{ if } x \geq 0 \\ 1.67326 * (\exp(x) - 1), & \text{ otherwise } \end{cases} \]

Examples:

x = tf.constant([-1, 0, 1], 'float32')
print(tf.keras.activations.selu(x, inplace=False))

Parameters:

• x (dragon.Tensor) – The input tensor.

Returns:

dragon.Tensor – The output tensor.
