silu#

ivy.silu(x, /, *, out=None)[source]#

Apply the silu function element-wise.

Parameters:

  • x (Union[Array, NativeArray]) – input array.

  • 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 containing the silu activation of each element in x.

Examples

With ivy.Array input:

>>> x = ivy.array([-1.0, 1.0, 2.0])
>>> y = ivy.silu(x)
>>> print(y)
ivy.array([-0.2689,  0.7310,  1.7615])

>>> x = ivy.array([-1.0, 1.0, 2.0])
>>> y = x.silu()
>>> print(y)
ivy.array([-0.2689,  0.7310,  1.7615])

>>> x = ivy.array([[-1.3, 3.8, 2.1], [1.7, 4.2, -6.6]])
>>> y = ivy.silu(x)
>>> print(y)
ivy.array([[-0.2784,  3.7168,  1.8708], [ 1.4374,  4.1379, -0.0089]])
Array.silu(self, /, *, out=None)[source]#

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

Parameters:

  • self (Array) – input array.

  • 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

Examples

>>> x = ivy.array([-1., 0., 1.])
>>> y = x.silu()
>>> print(y)
ivy.array([-0.26894143,  0.        ,  0.73105854])
Container.silu(self, /, *, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, out=None)[source]#

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

Parameters:

  • self (Container) – input container.

  • 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 rectified linear activation unit function applied element-wise.

Examples

>>> x = ivy.Container(a=ivy.array([1.0, -1.2]), b=ivy.array([0.4, -0.2]))
>>> y = x.silu()
>>> print(y)
{
    a: ivy.array([0.73105854, -0.27777028]),
    b: ivy.array([0.23947507, -0.0900332])
