Machine Learning with Small Data with Sarah Ostadabbas

What happens when artificial intelligence doesn’t have access to millions—or even thousands—of data points? In this episode, Dr. Sarah Ostadabbas, Associate Professor of Electrical & Computer Engineering at Northeastern University and Director of the Augmented Cognition Lab, makes the case for why the future of A.I. depends on learning from small data.

She explains how her team tackles high-stakes problems in healthcare, defense, and autonomous systems by using advanced techniques like transfer learning, domain adaptation, simulation, and collaboration with domain experts. From diagnosing rare diseases with only a few samples to off-road military vehicle training in extreme weather, Sarah illustrates how small data solutions are essential when data is scarce, private, or expensive to label.

We also discuss her upcoming Machine Learning with Small Data course, launching on Coursera in Summer 2025, which teaches industry professionals and researchers how to apply data-efficient A.I. in real-world settings.
