Top SchoolDingding Qian is a Senior Software Engineer based in Haidian District, Beijing, with over a decade of experience building data-driven ranking and advertising systems. Currently at Tencent, he applies cutting-edge techniques to personalize news ranking, drawing on deep prior work at Sogou where he developed CTR prediction features, implemented sparse optimization (OWL-QN/LBFGS), and built online learning pipelines (FTRL, BPR). He combines practical machine learning engineering—feature design, factorization machines, GBDT/DNN experiments—with production-focused algorithm optimization to deliver low-latency, scalable models. His background includes research-oriented training (Master’s in Computer Science) and early large-scale data analysis experience at Taobao, reflecting a blend of academic rigor and hands-on product impact. Notably, he has repeatedly bridged one-hot categorical representations and continuous feature engineering to improve nonlinear model performance in real-world ad and recommendation contexts.
