MI-Suite (Materials Informatics Suite)

MI-Suite consists of functions necessary for Materials Informatics (MI), such as a maximum common substructure search function, a descriptor calculation function, and an external database access tool, centered on the estimation of QSPR (Quantitative Structure-Property Relationship) using machine learning. J-OCTA also provides tools (e.g. modeling API, scenario functions, etc.) to support creating databases of physical quantities and properties by creating a large number of inputs and performing calculations. This allows for the possibility of using simulation results instead of experimental results to compensate for the lack of data needed for machine learning.

The selection of data to be used for machine learning and the setting of training conditions can be done from a dialog box, and there is no need for users to do any programming, so even novice users can start working on it immediately. In addition, several pre-trained models are included, and these models can be used for forecasting.
