About

Welcome!

I am a Ph.D. student in the computer science department at Virginia Tech. I work in the Machine Learning Laboratory, advised by Bert Huang. I am also a member of the Discovery Analytics Center (DAC) at Virginia Tech. I received my bachelor's degree in Computer Science from American University of Nigeria.

Research Interests

My research investigates new methods for weakly supervised learning with special focus on adversarial learning, structured prediction, and optimization.

Currently, I am working on adversarial learning for weak supervision. The aim of this work is to train models robust to noise and error dependencies amongst weak supervision signals. We combine adversarial learning with weak supervision to train models to perform well against output perturbations of the label distribution.
