| Outline of Final Research Achievements |
Boltzmann machines are an important stochastic model in machine learning, and a chaotic Boltzmann machine (CBM) model has been proposed using deterministic chaos. We have implemented this model by both analog and digital integrated circuits (ICs), evaluated their performance, and developed the circuit design technology that can be applied to deep-learning hardware. We have implemented an exponential function used in the CBM model by the characteristics of the subthreshold region of a MOSFET in analog ICs, and by bit shift operation in digital ICs, and verified the operation of CBMs using real IC chips. We have designed a 100-neuron CBM in a digital IC, applied it to max-cut problems, and verified the output of the optimum solutions.
