AIZOTH Inc. offers a wide range of AI services, including AI software provision, AI consulting, spot support for manufacturing condition optimization, and contract R&D. Multi-Sigma is a cloud-based AI software for R&D that digitizes R&D, significantly reduces experimental labor, and supports innovative discoveries, innovative discoveries. Already used by leading manufacturing companies and top universities, Multi-Sigma has the following features. Numerical analysis using deep learning techniques of neural networks and Bayesian analysis enables highly accurate multi-objective variable forecasting, factor analysis, and multi-objective optimization without over-learning, even with minimal data sets. As a no-code cloud-based software, it can be used by anyone on a browser, and AI-DOE (innovative design of experiments using artificial intelligence), materials informatics, and process informatics can also be easily implemented. It is highly versatile and can be used for R&D issues in the chemical and other manufacturing industries, as well as for sales forecasting, marketing, and other management issues.
