The GauchoAI team is based on the Natural Language Processing Group at UC Santa Barbara.
We study the theoretical foundation and practical algorithms for language, vision, and machine learning technologies. We tackle challenging learning and reasoning problems under uncertainty and pursue answers via studies of machine learning, deep learning, and interdisciplinary data science. Broadly, we are interested in designing scalable inference and learning algorithms to analyze massive datasets with complex structures. In particular, our team concentrates on the areas of deep learning, reinforcement learning, vision-and-language navigation, large multimodal pretraining models, video and language, and robot manipulation.
Jiachen L. — Team leader
Jiachen is a first-year PhD student at UC Santa Barbara advised by William Wang. He received his master's in electrical and computer engineering at University of California San Diego and a bachelor degree from Huazhong University of Science and Technology where he was an outstanding undergraduate in terms of academic performance (Top 1%). His current research interests broadly include Deep RL that tackles continuous control, and Multi-modal understanding.
Tsu-Jui (Ray) F.
Tsu-Jui is currently a third-year Ph.D. student at UCSB CS, advised by William Wang. His research interest lies in natural language processing (NLP) and computer vision (CV).
