I am primarily interested in machine learning and its applications to problems in robotics, assistive technologies, and human-computer interaction. I develop and apply new techniques for predicting structured data. I was awarded a Ph.D. in Machine Learning from Carnegie Mellon University in 2010.
Adversarial prediction: Approximating our training data and optimizing over the exact performance measure to provide greater flexibility for:
- Learning under covariate shift (input distribution bias) and active learning;
- Cost-sensitive classification and inductive optimization of univariate performance measures;
- Learning to optimize for F-measure, discounted cumulative gain, and other multivariate performance measures; and
- Structured prediction problems over sequences, trees, graphs, etc.
Inverse optimal control: Using maximum entropy structured prediction techniques to forecast future human behavior for intelligent robotics and vehicle navigation applications.
