Research Outline
Recent information technologies including machine learning and data science are being developed in a variety of research fields. The research center for smart information technology aims to develop basic research and applied research in such information technology areas.
Among all such areas, our main targets are knowledge representation, media processing/recognition, and real-world sensing as the basic research. Based on these basic technologies, we also focus on material informatics, mechanical informatics, and other interdisciplinary application areas.

- ■Iron is an essential material in the industry. The material is composed of many crystal grains, and the grain boundary, which is the interface between the grains, dramatically influences the material's overall mechanical properties. In this study, we used a neural network describing theinteraction of iron atoms to evaluate the properties of iron grain boundaries with high accuracy. As a result, the evaluation of grain boundary energy of iron, which was impossible with conventional methods, was realized with the precision of quantum mechanics.
[Estimation of Internal Stresses in High-Entropy Alloys]
-
■High-entropy alloys are alloys composed of a variety of elements. Their unique structure gives challenging to elucidate the mechanism of their funct them excellent mechanical properties, but it is ional manifestation. In this study, we applied the first-principles atomic stress calculation method together with Random Forest, a machine learning method, to elucidate the internal stress state and its expression mechanism in high-entropy alloys. We found that the internal stress state is governed by the charge transfer and volume change in individual atoms.
