Derek Chen

Derek Chen is a Research Scientist at ASAPP designing intelligent dialogue systems with stronger natural language understanding capabilities. He received his Masters in Computer Science from the University of Washington and his undergraduate degree from UC Berkeley. His research is focused on data efficiency methods including active learning, data augmentation and meta-learning. He is also interested in techniques surrounding uncertainty measurement so that a dialogue agent can better manage ambiguity and out-of-scope situations.
