To the extent that it's a new umbrella term that mostly encompasses a set of techniques that have been around for a couple decades now, yeah, it's just a rebranding. But I think the rebranding makes some sense because it calls attention to a common characteristic shared by all the techniques that fall under the brand: They tend to learn their own feature transformations, which is cool because it means you don't have to put nearly so much effort into figuring out how to curate the input.
