About

My latest research is on improving the processes by which humans teach and instruct computers. That includes learning to generalize from fewer examples, with methods like zero-shot and few-shot learning, as well as engineering training data, with methods like synthetic data generation and programmatic weak supervision. I measure that improvement in terms of reduction in the effort required by people---especially non-computer scientists in specialized, technical domains---to get computers to do what they want. Applications of our group's work include information extraction, image understanding, scientific discovery, and other areas of data science.
