RandomAugmentation1DPipeline 

RandomAugmentation1DPipeline(layers: list[BaseAugmentation1D], augmentations_per_sample: int = 1, rate: float = 1.0, batchwise: bool = False, force_training: bool = False, **kwargs)

Apply N random augmentations from a list of augmentation layers to each sample.

Parameters:

  • layers

    (list[BaseAugmentation1D]) –

    List of augmentation layers to choose from.

  • augmentations_per_sample

    (int, default: 1 ) –

    Number of augmentations to apply to each sample.

  • rate

    (float, default: 1.0 ) –

    Probability of applying the augmentation pipeline.

  • batchwise

    (bool, default: False ) –

    If True, apply same layer to all samples in the batch.

  • force_training

    (bool, default: False ) –

    Force training mode. Defaults to False.
