Correcting for Interference in Experiments: A Case Study at Douyin
Vivek F. Farias, Hao Li, Tianyi Peng +3
Interference is a ubiquitous problem in experiments conducted on two-sided content marketplaces, such as Douyin (China's analog of TikTok). In many cases, creators are the natural…
Markovian Interference in Experiments
Vivek F. Farias, Andrew A. Li, Tianyi Peng +1
We consider experiments in dynamical systems where interventions on some experimental units impact other units through a limiting constraint (such as a limited inventory). Despite…
Synthetically Controlled Bandits
Vivek Farias, Ciamac Moallemi, Tianyi Peng +1
This paper presents a new dynamic approach to experiment design in settings where, due to interference or other concerns, experimental units are coarse. `Region-split' experiments…
Uncertainty Quantification For Low-Rank Matrix Completion With Heterogeneous and Sub-Exponential Noise
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…
Learning Treatment Effects in Panels with General Intervention Patterns
Vivek F. Farias, Andrew A. Li, Tianyi Peng
The problem of causal inference with panel data is a central econometric question. The following is a fundamental version of this problem: Let be a low rank matrix and be…
Fixing Inventory Inaccuracies At Scale
Vivek F. Farias, Andrew A. Li, Tianyi Peng
Inaccurate records of inventory occur frequently, and by some measures cost retailers approximately 4% in annual sales. Detecting inventory inaccuracies manually is cost-prohibitiv…
The Limits to Learning a Diffusion Model
Jackie Baek, Vivek F. Farias, Andreea Georgescu +5
This paper provides the first sample complexity lower bounds for the estimation of simple diffusion models, including the Bass model (used in modeling consumer adoption) and the SI…
Simulating Large Quantum Circuits on a Small Quantum Computer
Tianyi Peng, Aram Harrow, Maris Ozols +1
Limited quantum memory is one of the most important constraints for near-term quantum devices. Understanding whether a small quantum computer can simulate a larger quantum system,…
