torchsig.transforms.base_transforms.Compose

class torchsig.transforms.base_transforms.Compose(transforms: list[Transform], **kwargs)

Bases: Transform

Composes several transforms together sequentially, in order.

This transform applies a sequence of transforms to the input signal.

transforms

List of Transform objects to be applied sequentially.

Methods

add_parent	Add parent Seedable object and set up RNGs accordingly.
get_distribution	Create distribution function with proper seeding.
get_second_seed	Gets second seed, usually used to seed both torch and numpy generators with slightly different seeds.
seed	Seed number generators with given seed.
setup_rngs	Initialize torch and numpy number generators, and update its children.
update_from_parent	Update numpy and torch number generators with parent seed.

__init__(transforms: list[Transform], **kwargs)

Initialize the Compose transform.

Parameters:

• transforms – List of Transform objects to be applied sequentially.

• **kwargs – Additional keyword arguments passed to the parent class.

__call__(signal: Signal) → Signal

Apply all transforms in sequence.

Parameters:

signal – Signal to be transformed.

Returns:

Transformed signal after applying all transforms.

__repr__() → str

Transform string representation.

Should be able to recreate class from this string.

Returns:

Transform representation.

__str__() → str

String representation of the transform.

Returns:

String representation of the transform.

add_parent(parent: Seedable) → None

Add parent Seedable object and set up RNGs accordingly.

Parameters:

parent – Parent Seedable object to add.

get_distribution(params: list | tuple | float, scaling: str = 'linear') → Distribution

Create distribution function with proper seeding.

Parameters:

• params – Parameters for distribution.

• scaling – Scaling param for distribution. Defaults to ‘linear’.

Returns:

Distribution function, seeded.

Return type:

Distribution

get_second_seed(seed: int) → int

Gets second seed, usually used to seed both torch and numpy generators with slightly different seeds.

Parameters:

seed – Seed to use.

Returns:

New seed.

seed(seed: int) → None

Seed number generators with given seed.

Parameters:

seed – Seed to use.

setup_rngs() → None

Initialize torch and numpy number generators, and update its children.

update_from_parent() → None

Update numpy and torch number generators with parent seed.
