Hello, thank you for such a great repo
I've trained the model and accuracy only achieve 30% ?
Could I ask you some questions:
Thank you for your contribution to the community! Personally, I found your neat implementation interesting and helpful!
By the way, is this current implementation following the Markov Property?
For instance, in MDPs, there is a state transition showing P(s' | s, a), right? And in RecSys setting, the state space consists of static and dynamic properties of users such as Static(User profile, eg., gender/age etc) and Dynamic(User's past activity, eg., click/non-click or view/purchase etc) so that we can correlate the states based on the action taken by an agent.
Looking at this implementation, it literally calculates the average of the ratings which I think it isn't dynamic over time and irrelevant to the occurrence of actions. could you help understand this part...?
