New materials/devices - Computing convergence application research is being conducted. It deals with phase change, resistance change, and 2D materials/devices for grafting applications such as artificial neural networks, optimization, and neuromorphic computing. The distinction of research lies in the intrinsic convergence of physicochemical characteristics of materials/devices into mathematical algorithms and arithmetics. In particular, using spontaneity, uncertainty, and complexity, parallel, ensemble, and probabilistic statistical operations are implemented and expanded to artificial intelligence computing.
