Cumulative reward meaning
WebApr 2, 2024 · I see what you mean: So, you're saying that maximizing the discounted average reward, step by step, is not the same as maximizing the discounted cumulative reward, step by step ? I think you are correct. My mistake. Still, it would be interesting to ask an expert what the actual statement regardiong equivalence is. Thank. $\endgroup$ – Webcumulative: [adjective] increasing by successive additions. made up of accumulated parts.

The reward is fundamental in RL because it’s the only feedback for the agent. Thanks to it, our agent knows if the action taken was good or not. The cumulative reward at each time step t can be written as: The cumulative reward equals to the sum of all rewards of the sequence. Which is equivalent to:
The cumulative reward at each time step t can be written as: Which is equivalent to: Thanks to Pierre-Luc Bacon for the correction. However, in reality, we can’t just add the rewards like that.
