About the Lab
We elucidate the theoretical foundations of machine learning and deep learning, and build on them to realize multimodal AI integrating heterogeneous data (imagery, weather signals, etc.) and advanced data-driven decision-making powered by large language models. We also train the next generation of data scientists through educational engineering, building society's AI infrastructure.
