Karl Astrom, a towering figure in control theory and pioneer of adaptive control, passed away on Nov 12 at age 92.
Babak Hassibi traces his legacy to modern ML: Astrom authored what is likely the first paper on controlling partially-observed Markov decision processes in 1965 — foundational to modern reinforcement learning — and his 1973 self-tuning regulators paper with Wittenmark laid the groundwork for "learning and control."
