Consider the sentence in the abstract of the paper at https://arxiv.org/abs/1610.09038.
Empirically we find that Professor Forcing acts as a regularizer, improving test likelihood on character level Penn Treebank and sequential MNIST.
I have used MNIST dataset. However, I could not find any Sequential MNIST or permuted MNIST datasets.
Are they standard datasets published anywhere or I can just permute by myself and call them permuted while the standard one is just called the Sequential one.
I guess the distinction in papers (of using the two versions -- permuted and sequential MNIST) must be due to some reason, what could be the reason? Is it some transfer learning thing?
