LAiW: A Chinese Legal Large Language Models Benchmark

1 code implementation9 Oct 2023 Yongfu Dai, Duanyu Feng, Jimin Huang, Haochen Jia, Qianqian Xie, Yifang Zhang, Weiguang Han, Wei Tian, Hao Wang

Through automated evaluation of current general and legal domain LLMs on our benchmark, we indicate that these LLMs may not align with the logic of legal practice.

Individual Causal Inference Using Panel Data With Multiple Outcomes

no code implementations3 Jun 2023 Wei Tian

Policy evaluation in empirical microeconomics has been focusing on estimating the average treatment effect and more recently the heterogeneous treatment effects, often relying on the unconfoundedness assumption.

The Synthetic Control Method with Nonlinear Outcomes: Estimating the Impact of the 2019 Anti-Extradition Law Amendments Bill Protests on Hong Kong's Economy

no code implementations3 Jun 2023 Wei Tian

The synthetic control estimator (Abadie et al., 2010) is asymptotically unbiased assuming that the outcome is a linear function of the underlying predictors and that the treated unit can be well approximated by the synthetic control before the treatment.

Synthetic Controls with Multiple Outcomes: Estimating the Effects of Non-Pharmaceutical Interventions in the COVID-19 Pandemic

no code implementations5 Apr 2023 Wei Tian, Seojeong Lee, Valentyn Panchenko

We propose a generalization of the synthetic control method to a multiple-outcome framework, which improves the reliability of treatment effect estimation.

Modeling and Joint Optimization of Security, Latency, and Computational Cost in Blockchain-based Healthcare Systems

no code implementations28 Mar 2023 Zukai Li, Wei Tian, Jingjin Wu

In the era of the Internet of Things (IoT), blockchain is a promising technology for improving the efficiency of healthcare systems, as it enables secure storage, management, and sharing of real-time health data collected by the IoT devices.
