Latest Patents

Nakaguchi is credited with 1 patent: “Learning device, learning method, and learning program.” The invention estimates a reward function through multiple importance sampling, using samples from a subject’s decision-making history and histories generated under a sampling policy. It then estimates a policy through reinforcement learning based on the reward function. The system can use the newly estimated policy as a sampling policy and repeat the reward-function estimation process.

Career Highlights

Nakaguchi’s listed patent reflects work on methods for learning from decision-making histories and iteratively improving policy estimates. His company affiliation is NEC Corporation.
