\Mathcal{o}}$ Revenue Regret
Revenue regret quantifies the difference between a decision-maker's actual revenue and the optimal revenue achievable in hindsight, often within dynamic environments like auctions or multi-agent reinforcement learning. Current research focuses on developing algorithms that minimize this regret under various constraints, such as limited policy updates (adaptivity constraints) or unknown market noise distributions, employing techniques like Thompson Sampling, Upper Confidence Bound (UCB) variations, and policy elimination. These advancements are significant for improving decision-making in online advertising, auction design, and other applications where sequential interactions and uncertainty are prevalent, leading to more efficient resource allocation and increased profitability.
