# elu#

ivy.elu(x, /, *, alpha=1.0, out=None)[source]#

Apply the elu unit function element-wise.

Parameters:
• x (`Union`[`Array`, `NativeArray`]) – Input array.

• alpha (`float`, default: `1.0`) – scaler for controlling the slope of the function for x <= 0 Default: 1.0

• out (`Optional`[`Array`], default: `None`) – optional output array, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

`Array`

Returns:

ret – The input array with elu applied element-wise.

Examples

With `ivy.Array` input: >>> x = ivy.array([0.39, -0.85]) >>> y = ivy.elu(x) >>> print(y) ivy.array([ 0.38999999, -0.57258511]) >>> x = ivy.array([1.5, 0.7, -2.4]) >>> y = ivy.zeros(3) >>> ivy.elu(x, out=y) >>> print(y) ivy.array([ 1.5, 0.69999999, -0.90928203]) >>> x = ivy.array([[1.1, 2.2, 3.3], … [-4.4, -5.5, -6.6]]) >>> ivy.elu(x, out=x) >>> print(x) ivy.array([[ 1.10000002, 2.20000005, 3.29999995],

[-0.98772264, -0.99591321, -0.99863964]])

With `ivy.Container` input: >>> x = ivy.Container(a=ivy.array([0.0, -1.2]), b=ivy.array([0.4, -0.2])) >>> x = ivy.elu(x, out=x) >>> print(x) {

a: ivy.array([0., -0.69880581]), b: ivy.array([0.40000001, -0.18126924])

}

Array.elu(self, /, *, alpha=1.0, out=None)[source]#

Ivy.Array instance method variant of ivy.elu. This method simply wraps the function, and so the docstring for ivy.elu also applies to this method with minimal.

Parameters:
• self – input array.

• alpha (`float`, default: `1.0`) – scaler for controlling the slope of the function for x <= 0 Default: 1.0

• out (`Optional`[`Array`], default: `None`) – optional output array, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

`Array`

Returns:

ret – an array with the elu activation function applied element-wise.

Examples

```>>> x = ivy.array([0.39, -0.85])
>>> y = x.elu()
>>> print(y)
ivy.array([ 0.39, -0.57])
```
Container.elu(self, /, *, alpha=1.0, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, out=None)[source]#

ivy.Container instance method variant of ivy.elu. This method simply wraps the function, and so the docstring for ivy.elu also applies to this method with minimal changes.

Parameters:
• self (`Container`) – input container.

• alpha (`Container`, default: `1.0`) – scaler for controlling the slope of the function for x <= 0 Default: 1.0

• key_chains (`Optional`[`Union`[`List`[`str`], `Dict`[`str`, `str`], `Container`]], default: `None`) – The key-chains to apply or not apply the method to. Default is `None`.

• to_apply (`Union`[`bool`, `Container`], default: `True`) – If True, the method will be applied to key_chains, otherwise key_chains will be skipped. Default is `True`.

• prune_unapplied (`Union`[`bool`, `Container`], default: `False`) – Whether to prune key_chains for which the function was not applied. Default is `False`.

• map_sequences (`Union`[`bool`, `Container`], default: `False`) – Whether to also map method to sequences (lists, tuples). Default is `False`.

• out (`Optional`[`Container`], default: `None`) – optional output container, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

`Container`

Returns:

ret – a container with the elu unit function applied element-wise.

Examples

```>>> x = ivy.Container(a=ivy.array([0.39, -0.85]), b=ivy.array([1., -0.2]))
>>> y = x.elu()
>>> print(y)
{
a: ivy.array([0.38999999, -0.57]),
b: ivy.array([1., -0.18])
}
