projects
LSTM-GRU Hybrid Network
Course Project, University of Science and Technology of China, Time Series Analysis, January, 2024
This is my final project for Time Series Analysis. I propose an LSTM-GRU hybrid network architecture, inspired by GoogLeNet, for PM2.5 time series forecasting, which reduced the error rate by 30% compared to LSTM.
Airbnb Price Prediction in New York City
Course Project, Duke University, CS 671 Theory & Alg Machine Learning, November, 2024
This project was my Kaggle competition in CS 671 (Machine Learning). The task was to predict Airbnb prices in New York City. I achieved a top 5 ranking out of 137 participants and later developed an improved solution outperforming all original submissions in the competition.
Amazon recommendation system - Report As a Data Scientist
Course Project, Duke University, STA 521 Predictive Inference, December, 2024
This is my final project for STA 521 (Predictive Inference), focusing on how to improve the effectiveness of recommendations using personal information on Amazon.
Basketball Breakdown - NCAA Shiny App
Course Project, Duke University, STA 523 R Programming, December, 2024
This is my group’s final project for STA 523 (R Programming): a data archive NCAA basketball data analysis Shiny app. It includes match, team, and player analysis, as well as visualization and prediction features.

research
TMfPOFD: Trimmed Mean for Partially Observed Functional Data
Bachelor's Thesis, University of Science and Technology of China, Mathematics Department, May, 2024
This is my bachelor’s thesis. In this thesis, I introduce the concept of the trimmed mean for partially observed functional data, prove the strong consistency of the estimator, and present results from simulation experiments.
SADA: Stability-guided Adaptive Diffusion Acceleration
ICML 2025, Duke University, January, 2025
A training-free diffusion acceleration framework that jointly exploits step-wise and token-wise sparsity via a unified stability criterion. SADA achieves ≥ 1.8× speedup while maintaining LPIPS ≤ 0.10 and FID ≤ 4.5, significantly outperforming prior methods on SD-2, SDXL, Flux, and ControlNet.
Enhanced Cyclic Coordinate Descent Methods for Elastic Net Penalized Linear Models
NeurIPS 2025 (Submitted), Duke University, May, 2025
A theoretically grounded optimization method that enhances classical coordinate descent by unrolling updates across blocks and applying Taylor-based curvature correction. ECCD achieves up to 13× speedup and maintains sub-10⁻⁵ relative error across logistic and Poisson GLMs, outperforming glmnet, biglasso, and ncvreg on high-dimensional benchmarks.
