Data attribution techniques quantify the influence of individual training examples on machine learning models, providing key insights for developing data-centric algorithms (e.g., data curation) as well as addressing data-related challenges (e.g., privacy, safety, and copyright protection).<div><br></div><div>In this talk, I will present our recent advances in the foundations and practical frameworks of data attribution. First, I will introduce a general, game-theoretic data attribution framework that optimizes for stochastic algorithms. I will then discuss how we can efficiently conduct data attribution in the challenging setting of large-scale deep learning models (e.g., large language models). These techniques guide data quality management, explain model predictions, and boost trustworthy AI development from a data-centric perspective. <br><br><b>Bio:</b> Jiachen ("Tianhao") is a Ph.D. student at Princeton University, advised by Prof. Prateek Mittal. His research focuses on developing theoretical foundations and practical tools for trustworthy machine learning from a data-centric perspective. Most recently, he has been developing scalable, theoretically grounded data attribution and curation techniques for foundation models. His contributions have been recognized through multiple fellowships and oral/spotlight presentations at top AI/ML venues. He was selected as a Rising Star in Data Science in 2024.<br><br><img id="<E65D0A0B-1350-477E-8828-D9979A0042FD>" src="cid:254361A9-B98B-41A6-85CE-5F8B012B677E" alt="headshot_Jiachen_Wang_1.jpeg" class="Apple-web-attachment"><br><br>Host: Raul Castro Fernandez<br><div><br></div><div>---</div><div>
