After three years of research and development and the demonstration of many Yi scholars, we succeeded in systematizing, quantifying and digitalizing many theories of the Book of Changes and Yuan Hai Ziping. Through the analysis and practice of eight characters, the data model of intelligent AI is corrected and corrected. Although the software looks rude, but the core is not simple. But as of today, we are the first and only team to successfully implement the quantified I Ching. Please give us understanding and time to improve. If the future development of data model is successful, we can use this quantitative data model to carry out large-scale data analysis, prospects and evaluation in many fields, benefiting millions of households. In the future, we will continue to improve it. We strive to develop the first Reasoning Intelligent AI data model in history. The intelligent AI of the Alpha Dog can win the Go championship. Similarly, the intelligent reasoning over-computed AI can be produced by the mathematical calculation of the Book of Changes. Win the crown of future big data analysis.
