Summary
👤
Senior🎓
Top SchoolYiyou Sun is a postdoctoral researcher at UC Berkeley with 11 years of experience bridging academic rigor and industry research in machine learning, following a PhD in Computer Science from the University of Wisconsin–Madison. His work focuses on building reliable open-world ML systems through out-of-distribution detection, open-world representation learning that discovers hidden classes, and interpretable model design that emphasizes sparsity and modularity. He brings hands-on experience from research internships at Google and Meta and a researcher role at NEC Labs, translating cutting-edge theory into practical systems. Based in Emeryville, CA, Yiyou combines deep technical expertise in visual model interpretability with a knack for uncovering structure in unexpected data—pursuing models that not only detect novelty but also explain and incorporate it.
