Sc\. in DS @ SUSTech **Profession:** 实习生 **Location:** Pittsburgh, Pennsylvania, United States ## About Tianyu Li is an incoming Master of Computational Data Science student at Carnegie Mellon University, pursuing opportunities as a Machine Learning Engineer or Applied Scientist intern for Summer 2027\. Tianyu holds a Bachelor of Science in Data Science from the Southern University of Science and Technology and has experience building scalable machine\-learning and NLP systems, from model development through production deployment\. At Tencent Music Entertainment, Tianyu developed an end\-to\-end text\-classification pipeline using StructBERT and focal loss for large\-scale, imbalanced user data, raising validation F1\-score from 72% to more than 82%, and deployed the model in a Linux production environment with Docker, Flask, and Gunicorn\. Tianyu has also applied large language models at PACE Solutions Limited, using the Claude API and refined prompt templates to translate insurance documents and extract structured information\. In undergraduate research, Tianyu led engineering of a hyperspectral image\-compression architecture that improved performance by 26% over existing baselines and resulted in publication in IEEE Transactions on Geoscience and Remote Sensing\. Tianyu’s academic projects also include PyTorch and Gaussian Splatting work in high\-dimensional image compression and 3D scene reconstruction\. ## Services - 机器学习 - 深度学习 - 计算机视觉 - Large Language Models \(LLM\) - 自然语言处理 - 图像处理 - 大数据分析 - 统计模型 - 数据结构 - 时间序列分析 - PyTorch - 研究 - 模型部署 - 提示写作 - 数据科学 - 机器翻译 - AI ## Highlights - Incoming Master of Computational Data Science student at Carnegie Mellon University\. - Holds a Bachelor of Science in Data Science from the Southern University of Science and Technology\. - Seeking Machine Learning Engineer or Applied Scientist internship opportunities for Summer 2027\. - Built an end\-to\-end Tencent Music Entertainment text\-classification pipeline using StructBERT and focal loss for large\-scale, imbalanced user data\. - Improved validation F1\-score from 72% to over 82% at Tencent Music Entertainment\. - Deployed a Tencent Music Entertainment model to a Linux production environment using Docker, Flask, and Gunicorn\. - Applied the Claude API at PACE Solutions Limited to translate insurance documents from English to Traditional Chinese\. - Created and refined prompt templates at PACE Solutions Limited to extract structured financial rules and basic policy details from backend systems\. - Led engineering of a novel hyperspectral image\-compression architecture during undergraduate research\. - Achieved a 26% performance improvement over existing hyperspectral image\-compression baselines\. - Published hyperspectral image\-compression research findings in IEEE Transactions on Geoscience and Remote Sensing \(IEEE TGRS\)\. - Completed academic projects involving PyTorch, Gaussian Splatting, high\-dimensional image compression, and 3D scene reconstruction\. - Attended the Berkeley International Study Program at the University of California, Berkeley as a visiting student in CS and STAT\. ## Experience - **实习生 at PACE \| Intelligent Life Insurer** (2025\-10\-01–2025\-12\-01) — As an AI Intern at PACE Solutions Limited, my main focus was applying Large Language Models to practical text processing tasks\. I utilized the Claude API to translate insurance documents from English to Traditional Chinese\. To make this process more efficient, I created and refined prompt templates that helped extract structured financial rules and basic policy details from existing backend systems\. - **Project Intern at 腾讯音乐** (2025\-06\-01–2025\-07\-01) — As a Machine Learning Engineering \(MLE\) project Intern at Tencent Music Entertainment, I focused on building and deploying robust NLP solutions for the Smart Platform Group\. I developed an end\-to\-end text classification pipeline utilizing StructBERT and focal loss to effectively process large\-scale, imbalanced user data\. Through this approach, I successfully boosted our validation F1\-score from 72% to over 82%\. Beyond just training the model, I took ownership of the MLOps and deployment phases\. I deployed the trained model directly into our Linux production environment using Docker, Flask, and Gunicorn, establishing a reliable and scalable serving infrastructure to handle real\-world traffic\. ## Education - Master of Computational Data Science — Carnegie Mellon University (2026\-08\-01–2027\-12\-01) - Bachelor of Science \- BS, Data Science — Southern University of Science and Technology (2022\-08\-01–2026\-06\-01) - Visiting student, Berkeley International Study Program, CS & STAT — University of California, Berkeley (2025\-08\-01–2025\-12\-01) - Chengdu NO\.7 High School 成都市第七中学 (2019\-08\-01–2022\-06\-01) ## FAQ ### What does Tianyu do now?
