| Abstract: | Based on the research of AI involved in FDD and data approach, The paper has presented a new algorithm for formula discovery from a large amount of experimental data. And then we build up the system by using the algorithm based on space of operators. The basic rules of operators are simplified, and the other three rules: derivative rule, inaccuracy rule and end rule, are introduced, which extend the knowledge lib and make it easy to use the rules in lib. Through the above improvement more forms and complexity of functional formulas are found than BACON and FDD system. In the end, the simulation result is given. |
