Eligibility traces
WebAs mentioned in eligibility traces (p25), the disadvantage of Watkins' Q (λ) is that in early learning, the eligibility trace will be “cut” (zeroed out) frequently, resulting in little advantage to traces. Maybe that's the reason why your Q-learning and Q … http://incompleteideas.net/book/ebook/node74.html
