RandAugment performs the Rand Augment operation on input images.

This layer can be thought of as an all-in-one image augmentation layer. The policy implemented by this layer has been benchmarked extensively and is effective on a wide variety of datasets.

Usage

layer_rand_augment(
  object,
  value_range = list(0L, 255L),
  num_ops = 2L,
  factor = 0.5,
  interpolation = "bilinear",
  seed = NULL,
  data_format = NULL,
  ...
)

Arguments

object

Object to compose the layer with. A tensor, array, or sequential model.

value_range

The range of values the input image can take. Default is (0, 255). Typically, this would be (0, 1) for normalized images or (0, 255) for raw images.

num_ops

The number of augmentation operations to apply sequentially to each image. Default is 2.

factor

The strength of the augmentation as a normalized value between 0 and 1. Default is 0.5.

interpolation

The interpolation method to use for resizing operations. Options include nearest, bilinear. Default is bilinear.

seed

Integer. Used to create a random seed.

data_format

String, one of "channels_last" (default) or "channels_first". The ordering of the dimensions in the inputs. "channels_last" corresponds to inputs with shape (batch, height, width, channels) while "channels_first" corresponds to inputs with shape (batch, channels, height, width).

...

For forward/backward compatability.
