Interactive $360^{\circ}$ Video Streaming Using FoV-Adaptive Coding with Temporal Prediction

no code implementations17 Mar 2024 Yixiang Mao, Liyang Sun, Yong liu, Yao Wang

We develop a low-latency FoV-adaptive coding and streaming system for interactive applications that is robust to bandwidth variations and FoV prediction errors.

Temporal Aggregation for the Synthetic Control Method

no code implementations22 Jan 2024 Liyang Sun, Eli Ben-Michael, Avi Feller

The synthetic control method (SCM) is a popular approach for estimating the impact of a treatment on a single unit with panel data.

Using Multiple Outcomes to Improve the Synthetic Control Method

no code implementations27 Nov 2023 Liyang Sun, Eli Ben-Michael, Avi Feller

When there are multiple outcome series of interest, Synthetic Control analyses typically proceed by estimating separate weights for each outcome.

Weak Identification with Many Instruments

no code implementations18 Aug 2023 Anna Mikusheva, Liyang Sun

We propose a test that properly partials out many exogenous regressors while preserving the re-centering property of the jack-knife.

Adapting to Misspecification

1 code implementation23 May 2023 Timothy B. Armstrong, Patrick Kline, Liyang Sun

Empirical research typically involves a robustness-efficiency tradeoff.

Empirical Welfare Maximization with Constraints

no code implementations29 Mar 2021 Liyang Sun

When designing eligibility criteria for welfare programs, policymakers naturally want to target the individuals who will benefit the most.

Inference with Many Weak Instruments

no code implementations26 Apr 2020 Anna Mikusheva, Liyang Sun

Large-sample inference based on the jackknifed AR is valid under heteroscedasticity and weak identification.

Double Robustness for Complier Parameters and a Semiparametric Test for Complier Characteristics

1 code implementation10 Sep 2019 Rahul Singh, Liyang Sun

We propose a semiparametric test to evaluate (i) whether different instruments induce subpopulations of compliers with the same observable characteristics on average, and (ii) whether compliers have observable characteristics that are the same as the full population on average.
