Since I am relatively new to the field of reinforcement learning and I read through the classic book Reinforcement Learning: An Introduction by Sutton et. al., in Chapter 9 the authors mention several methods for feature construction, i.e. polynomial basis, Fourier basis functions, tile coding, etc.
My question is: are there good code bases or papers that apply these abstract principles to real problems, meaning games or robotic tasks? It would be great to get a better sense of how to construct features for one's own projects and it seems like a great learning experience to see illustrations of successful feature constructions.
Thanks in advance.
