DEVICE, METHOD AND PROGRAM FOR ACQUIRING FEATURE DATA FOR MATERIAL COMPOSITION INFORMATION BASED ON ARTIFICIAL INTELLIGENCE

A system, device, method, and program for acquiring feature data for material composition information based on artificial intelligence are disclosed. The system may include a memory configured to store a first artificial intelligence (AI) model configured to output first feature data for composition information of a material and a second AI model configured to output second feature data for structure information of the material; and a processor configured to learn the first AI model and the second AI model. The processor may be configured to learn the first AI model based on the second feature data for the structure information of the material output by the second AI model, and/or to learn the second AI model based on the first feature data for the composition information of the material output by the first AI model.
