University of Michigan · Computer Science

I am a Ph.D. student in Computer Science at the University of Michigan. My research focuses on uncertainty quantification for sequential prediction — particularly the design of reliable predictive sets and intervals for non-stationary time series. My work spans conformal prediction, causal inference, and applications in epidemiology and public health, weather forecasting, and autonomous driving.

Neural Conformal Control for Time Series Forecasting

Ruipu Li and Alexander Rodríguez

Introduces a neural conformal prediction framework for time series that adapts to non-stationary environments. Leverages auxiliary multi-view encoders end-to-end, enforces monotonicity constraints for consistent prediction intervals across quantiles, and supports few-shot learning via related-task data. Achieves state-of-the-art coverage and calibration across epidemic, weather, and energy demand benchmarks.

Optimization-based Online Conformal Prediction for Multi-step Forecasting

Ruipu Li, Diego Menacho, and Alexander Rodríguez

Proposes a unified conformal prediction framework that converts ensemble trajectory samples into calibrated prediction intervals with formal coverage guarantees. Introduces an online update step and an optimization step that explicitly captures inter-step temporal dependencies, yielding sharper and more adaptive uncertainty estimates across autonomous driving, hurricane forecasting, and epidemic modeling.
