The RandomCrop(t,shape,opts) command constructs a Tensor with shape shape by randomly slicing data from t with uniform probability.

The RandomShuffle(t,opts) command randomly shuffles a Tensor along its first dimension.

The DeepLearning/Tensor/RandomCrop and DeepLearning/Tensor/RandomShuffle commands were introduced in Maple 2018.
