Robust Budget Pacing with a Single Sample

no code implementations3 Feb 2023 Santiago Balseiro, Rachitesh Kumar, Vahab Mirrokni, Balasubramanian Sivan, Di Wang

Given the inherent non-stationarity in an advertiser's value and also competing advertisers' values over time, a commonly used approach is to learn a target expenditure plan that specifies a target spend as a function of time, and then run a controller that tracks this plan.

Online Resource Allocation under Horizon Uncertainty

no code implementations27 Jun 2022 Santiago Balseiro, Christian Kroer, Rachitesh Kumar

We go on to give a fast algorithm for computing a schedule of target consumption rates that leads to near-optimal performance in the unknown-horizon setting.

Single-Leg Revenue Management with Advice

no code implementations18 Feb 2022 Santiago Balseiro, Christian Kroer, Rachitesh Kumar

Moreover, we provide an online algorithm that always achieves performance on this Pareto frontier.

Mechanism Design under Approximate Incentive Compatibility

no code implementations5 Mar 2021 Santiago Balseiro, Omar Besbes, Francisco Castro

We establish that the gains that can be garnered depend on the local curvature of the seller's revenue function around the optimal posted price when the buyer is a perfect optimizer.

The Best of Many Worlds: Dual Mirror Descent for Online Allocation Problems

no code implementations18 Nov 2020 Santiago Balseiro, Haihao Lu, Vahab Mirrokni

In this paper, we consider a data-driven setting in which the reward and resource consumption of each request are generated using an input model that is unknown to the decision maker.

Regularized Online Allocation Problems: Fairness and Beyond

no code implementations1 Jul 2020 Santiago Balseiro, Haihao Lu, Vahab Mirrokni

In this paper, we introduce the \emph{regularized online allocation problem}, a variant that includes a non-linear regularizer acting on the total resource consumption.

Dual Mirror Descent for Online Allocation Problems

no code implementations ICML 2020 Haihao Lu, Santiago Balseiro, Vahab Mirrokni

The revenue function and resource consumption of each request are drawn independently and at random from a probability distribution that is unknown to the decision maker.

Contextual Bandits with Cross-learning

no code implementations NeurIPS 2019 Santiago Balseiro, Negin Golrezaei, Mohammad Mahdian, Vahab Mirrokni, Jon Schneider

We consider the variant of this problem where in addition to receiving the reward $r_{i, t}(c)$, the learner also learns the values of $r_{i, t}(c')$ for some other contexts $c'$ in set $\mathcal{O}_i(c)$; i. e., the rewards that would have been achieved by performing that action under different contexts $c'\in \mathcal{O}_i(c)$.

Dynamic Revenue Sharing

no code implementations NeurIPS 2017 Santiago Balseiro, Max Lin, Vahab Mirrokni, Renato Leme, Iiis Song Zuo

In this paper, we characterize the optimal revenue sharing scheme that satisfies both constraints in expectation.
