    Technical Projects

    AlphaBuild: Generating Formulaic Alphas on a Wider Range of Stock Data

    Leading AlphaBuild as the final project of course AI1803, an RL-based methodology using PPO to optimize factor mining based on AlphaGen, achieving superior backtest performance by leveraging smaller, parallel factor pools and PCA for final factor selection.

    Data Structure Awesome
    https://github.com/xiyuanyang-code/Data-Structure-Awesome

    C++ implementations of various data structures and classic algorithms. As the final project for CS0501H (with ACM Honor Class students), I implemented several STL containers, including std::vector, std::list, std::priority_queue, std::linked_hashmap and std::map.

    Voice Translation
    https://github.com/xiyuanyang-code/voice_translation

    Developed a Vosk-based Chinese-English Bilingual Speech Recognition Application that implements real-time speech-to-text functionality, accurately transcribing spoken language across both Chinese and English in a dynamic, real-time environment.
