He was influenced by Harry Klopf's work in the 1970s, which proposed that supervised learning is insufficient for AI or explaining intelligent behavior, and trial-and-error learning, driven by "hedonic aspects of behavior", is necessary. This focussed his interest to reinforcement learning.[5]
From 1998 to 2002, Sutton worked at the AT&T Shannon Laboratory in Florham Park, New Jersey as principal technical staff member in the artificial intelligence department.[3]
Since 2003, he has been a professor of computing science at the University of Alberta. He led the institution's Reinforcement Learning and Artificial Intelligence Laboratory until 2018.[6][3]
While retaining his professorship, Sutton joined Deepmind in June 2017 as a distinguished research scientist and co-founder of its Edmonton office.[4][7][8]
Sutton became a Canadian citizen in 2015 and renounced his US citizenship[8] in 2017.
In a 2019 essay, Sutton criticized the field of AI research for failing "to learn the bitter lesson that building in how we think we think does not work in the long run", arguing that "70 years of AI research [had shown] that general methods that leverage computation are ultimately the most effective, and by a large margin", beating efforts building on human knowledge about specific fields like computer vision, speech recognition, chess or Go.[9][10]
In 2023 he and John Carmack announced a partnership for the development of AGI.[11]
For significant contributions to many topics in machine learning, including reinforcement learning, temporal difference techniques, and neural networks.
In 2016, Sutton was elected Fellow of the Royal Society of Canada.[15] In 2021, he was elected Fellow of the Royal Society.[16]
