| Outline of Final Research Achievements |
This study is to develop an innovative algorithm in the field of machine learning that uses classical stochastic processes, based on the fact that the convergence to steady state accelerates when the detailed balance is broken.
Starting with Physical Review E 93 (2016) 012129 in 2016, we understand the role played by detailed balance as a physical process, go beyond classical stochastic processes, and step into quantum stochastic processes to create diverse algorithms I aimed at. The basic theory for exploiting quantum systems that are difficult to handle due to the presence of the negative sign problem was developed in Scientific Reports, (2017) 41186, and in scientific reports, 8 (2018) 9950, machine learning utilizing quantum fluctuation A demonstration experiment of the algorithm was conducted.

| Academic Significance and Societal Importance of the Research Achievements |
機械学習の発展は現代科学の礎を築く上で最重要課題であり、その物理学的視座に基づく新規アルゴリズム創出は、決して発見論的ではなく、検証可能であり確固たる理論体系の元に築き上げられる。場当たり的な手法ではない普遍的な手法となるため、その構造の理解と手法の水平展開の容易さから、今後10年に渡る研究の展開の起点となることが期待される。
