I have been reading the Reinforcement Learning textbook for the past three years religiously- didn’t get the concepts clear until this week, made it past Chapter 3 finally. The excellent YT lectures by David Silver and Emma Brunskill have been helpful but it took me a long time to ‘get it’.
Next, I will try to build something using RL next but try not to use the Gym/Farama stuff to force myself to learn this from scratch.
