About the Lab

The Laboratory for Robust and Efficient Machine Learning (REML) is directed by Prof. Benjamin M. Marlin in the College of Information and Computer Sciences at the University of Massachusetts Amherst.

The REML Lab focuses on making machine learning models and algorithms more robust and efficient for use in challenging deployment scenarios. The Lab conducts research on multiple aspects of robustness including robustness to noise, missing data, low labeled data volumes, and the potential for out-of-distribution and adversarial examples. The Lab has a particular emphasis on solving these problems in the context of accuracy-speed-storage-communication trade-offs motivated by embedded, cloud-assisted and and other real-time deployment scenarios.

The lab pursues research on a variety of solutions to these problems founded on principles of probabilistic machine learning. Current research includes fusions of probabilistic and deep learning models for learning from incomplete and irregularly sampled data, the study of active learning and zero-shot learning for improving predictive performance in the low labeled data setting, and the study of computationally efficient Bayesian deep learning methods for deployment in resource constrained settings.

The Lab’s research is informed by multiple real-world applications domains and machine learning deployment contexts including clinical and mobile health, embedded systems, and the Internet of Things. The lab is deeply engaged in large-scale interdisciplinary research projects and collaborates with computer scientists, engineers, statisticians, behavioral scientists and clinicians locally and across the country.
