Should I model this problem as a POMDP?
Suppose we have a finite-horizon sequential decision-making problem. At period $t$ we are in state $s$. We take action $a$ and we receive reward $r$ and go to state $s-1$ at period $t+1$. However, it ...

How to improve the reward signal when the rewards are sparse?
In cases where the reward is delayed, this can negatively impact a models ability to do proper credit assignment. In the case of a sparse reward, are there ways in which this can be negated?
In a ...

How to deal with the time delay in reinforcement learning?
I have a question regarding the time delay in reinforcement learning (RL).
In the RL, one has state, reward and action. It is usually assumed that (as far as I understand it) when the action is ...
