The Transient Cost of Learning in Queueing Systems
Daniel Freund, Thodoris Lykouris, Wentao Weng
Queueing systems are widely applicable stochastic models with use cases in communication networks, healthcare, service systems, etc. Although their optimal control has been extensi…
Towards Practical Robustness Auditing for Linear Regression
Daniel Freund, Samuel B. Hopkins
We investigate practical algorithms to find or disprove the existence of small subsets of a dataset which, when removed, reverse the sign of a coefficient in an ordinary least squa…
On the Power of Delayed Flexibility: Balls, Bins, and a Few Opaque Promotions
Daniel Freund, Chamsi Hssaine, Jiayu Kamessi Zhao
Effective load balancing lies at the heart of many applications in operations. Frequently tackled via the balls-into-bins paradigm, seminal results established the power of two cho…
Efficient decentralized multi-agent learning in asymmetric bipartite queueing systems
Daniel Freund, Thodoris Lykouris, Wentao Weng
We study decentralized multi-agent learning in bipartite queueing systems, a standard model for service systems. In particular, N agents request service from K servers in a fully d…
Overbooking with bounded loss
Daniel Freund, Jiayu Kamessi Zhao
We study a classical problem in revenue management: quantity-based single-resource revenue management with no-shows. In this problem, a firm observes a sequence of customers re…
Fair Incentives for Repeated Engagement
Daniel Freund, Chamsi Hssaine
We study a decision-maker's problem of finding optimal monetary incentive schemes for retention when faced with agents whose participation decisions (stochastically) depend on the…
Driver Positioning and Incentive Budgeting with an Escrow Mechanism for Ridesharing Platforms
Hao Yi Ong, Daniel Freund, Davide Crapis
Drivers on the Lyft rideshare platform do not always know where the areas of supply shortage are in real time. This lack of information hurts both riders trying to find a ride and…
Minimizing Multimodular Functions and Allocating Capacity in Bike-Sharing Systems
Daniel Freund, Shane G. Henderson, David B. Shmoys
The growing popularity of bike-sharing systems around the world has motivated recent attention to models and algorithms for their effective operation. Most of this literature focus…
Pricing and Optimization in Shared Vehicle Systems: An Approximation Framework
Siddhartha Banerjee, Daniel Freund, Thodoris Lykouris
Optimizing shared vehicle systems (bike/scooter/car/ride-sharing) is more challenging compared to traditional resource allocation settings due to the presence of \emph{complex netw…
Rank Aggregation: New Bounds for MCx
Daniel Freund, David P. Williamson
The rank aggregation problem has received significant recent attention within the computer science community. Its applications today range far beyond the original aim of building m…
Contagious Sets in Dense Graphs
Daniel Freund, Matthias Poloczek, Daniel Reichman
We study the activation process in undirected graphs known as bootstrap percolation: a vertex is active either if it belongs to a set of initially activated vertices or if at some…
