elu
(
x,
alpha=1.0,
**kwargs
)[source]¶Apply the exponential linear unit to input. [Clevert et.al, 2015].
The ELU function is defined as:
\[\text{ELU}(x) = \begin{cases} x, & \text{ if } x \geq 0 \\ \alpha * (\exp(x) - 1), & \text{ otherwise } \end{cases} \]Examples:
x = tf.constant([-1, 0, 1], 'float32') print(tf.keras.activations.elu(x, inplace=False))
- Parameters:
- x (dragon.Tensor) – The input tensor.
- alpha (float, optional, default=1.) – The value to \(\alpha\).
- Returns:
dragon.Tensor – The output tensor.
