Best of Many in Both Worlds: Online Resource Allocation with Predictions under Unknown Arrival Model

no code implementations21 Feb 2024 Lin An, Andrew A. Li, Benjamin Moseley, Gabriel Visotsky

We take the shadow price of each resource as prediction, which can be obtained by predictions on future requests.

Modeling Choice via Self-Attention

no code implementations11 Nov 2023 Joohwan Ko, Andrew A. Li

Naturally, accurate estimation of these models from data is a critical step in the application of these optimization problems in practice.

Markovian Interference in Experiments

no code implementations6 Jun 2022 Vivek F. Farias, Andrew A. Li, Tianyi Peng, Andrew Zheng

We consider experiments in dynamical systems where interventions on some experimental units impact other units through a limiting constraint (such as a limited inventory).

Uncertainty Quantification For Low-Rank Matrix Completion With Heterogeneous and Sub-Exponential Noise

no code implementations22 Oct 2021 Vivek F. Farias, Andrew A. Li, Tianyi Peng

The problem of low-rank matrix completion with heterogeneous and sub-exponential (as opposed to homogeneous and Gaussian) noise is particularly relevant to a number of applications in modern commerce.

Low-Rank Matrix Completion Uncertainty Quantification

Optimizing Offer Sets in Sub-Linear Time

no code implementations17 Nov 2020 Vivek F. Farias, Andrew A. Li, Deeksha Sinha

Personalization and recommendations are now accepted as core competencies in just about every online setting, ranging from media platforms to e-commerce to social networks.

Dimensionality Reduction

Fixing Inventory Inaccuracies At Scale

no code implementations23 Jun 2020 Vivek F. Farias, Andrew A. Li, Tianyi Peng

Using synthetic data and real data from a consumer goods retailer, we show that our approach provides up to a 10x cost reduction over incumbent approaches to anomaly detection.

Causal Inference With Selectively Deconfounded Data

no code implementations25 Feb 2020 Kyra Gan, Andrew A. Li, Zachary C. Lipton, Sridhar Tayur

In this paper, we consider the benefit of incorporating a large confounded observational dataset (confounder unobserved) alongside a small deconfounded observational dataset (confounder revealed) when estimating the ATE.
