Colorful Pinball: Density-Weighted Quantile Regression for Conditional Guarantee of Conformal Prediction
Qianyi Chen, Bo Li
Although conformal prediction provides robust marginal coverage guarantees, achieving reliable conditional coverage for specific inputs remains challenging. While exact distributio…
Journey to the Centre of Cluster: Harnessing Interior Nodes for A/B Testing under Network Interference
Qianyi Chen, Anpeng Wu, Bo Li +2
A/B testing on platforms often faces challenges from network interference, where a unit's outcome depends not only on its own treatment but also on the treatments of its network ne…
Just Ramp-up: Unleash the Potential of Regression-based Estimator for A/B Tests under Network Interference
Qianyi Chen, Bo Li
Recent research in causal inference under network interference has explored various experimental designs and estimation techniques to address this issue. However, existing methods,…
Practical Performative Policy Learning with Strategic Agents
Qianyi Chen, Ying Chen, Bo Li
This paper studies the performative policy learning problem, where agents adjust their features in response to a released policy to improve their potential outcomes, inducing an en…
