Research Thrust 1: Foundations

This thrust develops the core principles for optimizing AI models to learn, reason, and generalize more effectively and efficiently. It spans adaptive post-training and test-time optimization, efficient representation learning and model compression, out-of-distribution generalization in structured domains, and trustworthy intelligence through methods such as activation steering and ecosystem-wide watermarking.
