WebThey are being used implicitly through eligibility traces, which allow for an efficient online implementation (the "backward view"). I do indeed have the impression that such uses are fairly rare in recent research though. I haven't personally played around with policy gradient methods to tell from personal experience why that would be. http://incompleteideas.net/book/ebook/node72.html
