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 ...

Can reinforcement learning be used for tasks where only one final reward is received?

Is reinforcement learning problem adaptable to the setting when there is only one - final - reward. I am aware of problems with sparse and delayed rewards, but what about only one reward and a quite ...
