  • PROJECTS & INTERNSHIP

    Exploiting Offline Dataset to Improve Online Bandit Learning Efficiency with Relative Feedback
    Shenzhen, China
    PI: Prof. Fang Kong, SUSTech
    Sep. 2024 - Apr. 2025
  • Conducted a comprehensive literature review on the state-of-the-art bandit algorithms, focusing on estimating model parameters using offline stochastic data for online preference feedback by accommodating the LinUCB algorithm.
  • Proposed several algorithmic approaches and conducted regret analysis, mathematically demonstrating that the offline dataset can effectively reduce regret within the proposed algorithm framework.
  • Delivered a seminar presentation on stochastic linear bandits based on Bandit Algorithms [Tor Latimore et al, chapter 19].

  • TAPALL
    Shenzhen, China
    Student Intern
    Jun. 2024 - Aug. 2024
  • Scraped 20,000+ uncopyrighted videos from several websites (Pikwizard, Vecteezy, Mazwai, etc.) through Beautiful Soup using Python; designed a video filtering algorithm to select the videos with flat surface, camera in motion from the dataset for product demonstration in various environments, and classify them into several predetermined categories.
  • Enabled the migration of two key business operations (3D Modeling and Digital Human) to the cloud by configuring a robust Python environment, replacing legacy on-premises systems.
  • Developed a cloud scheduling system to implement the company's 3D Modelling and Digital Human solutions, reduced back-end operational expenses by implementing elastic GPU deployment instead of engaging in long-term leasing.

  • Nature Index Periodicals: A Comparative Analysis of Impact and Innovation in Publications
    Shenzhen, China
    PI: Prof. Yifang Ma, SUSTech
    Jun. 2022 - Aug. 2023
  • Collected 21,848 journal information from over 10 million papers from the Web of Science and a private database, featuring paper indexes like conventionality, hit5, hotspot, and novelty.
  • Visualized KDE plots for over 1.5 million papers in NI and non-NI journals with similar journal impact factors in the same field, finding that NI journals do not exhibit an advantage in novelty.
  • Analyzed the affiliations and publications in NI and non-NI journals, concluding that NI journals tend to favor works from institutions in the U.S. and Europe. Suggesting either a limitation in the Nature Index's ability to differentiate highly influential journals or an inherent bias in the selection practices of publishers.
