MixUp implements the MixUp data augmentation technique.
layer_mix_up(object, alpha = 0.2, data_format = NULL, seed = NULL, ...)Object to compose the layer with. A tensor, array, or sequential model.
Float between 0 and 1. Controls the blending strength. Smaller values mean less mixing, while larger values allow for more blending between images. Defaults to 0.2, recommended for ImageNet1k classification.
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).
Integer. Used to create a random seed.
For forward/backward compatability.
c(c(images, labels), .) %<-% dataset_cifar10()

labels <- labels |> op_one_hot(10) |> op_cast("float32")
