AQuA: Recursively Self-Improving Quantitative Trading Research Agents
Jiacheng Guo, Suozhi Huang, Yunlong Gao +5
We study recursive self-improvement at the level of quantitative-investment research: whether an autonomous system can use evidence from earlier experiments to improve the hypothes…
What is the Long-Term Value of Reliability?
Chenyu Qiu, Xu Kuang, Inessa Liskovich +2
We describe Chronos LTV, a system to measure the long-term impact of delays and other service defects on key business metrics. We use Markov decision processes to model customer in…
Behavioral Generative Agents for Energy Operations
Cong Chen, Omer Karaduman, Xu Kuang
Problem definition: Accurately modeling consumer behavior in energy operations is challenging due to uncertainty, behavioral heterogeneity, and limited empirical data-particularly…
Prioritizing Recurrent Services
Lin Franklin Feng, Yue Hu, Xu Kuang
We study optimal scheduling in multi-class queueing systems with reentrance, where jobs may return for additional service after completion. Such reentrance creates feedback loops t…
Learning Service Slowdown using Observational Data
Xu Kuang, Gal Mendelson
Being able to identify service slowdowns is crucial to many operational problems. We study how to use observational congestion data to learn service slowdown in a multi-server syst…
Treatment Effects in Market Equilibrium
Evan Munro, Xu Kuang, Stefan Wager
Policy-relevant treatment effect estimation in a marketplace setting requires taking into account both the direct benefit of the treatment and any spillovers induced by changes to…
