| 摘要: |
| 在FDD提出的人工智能技术与曲线拟合技术结合的公式发现系统的基础上, 提出了新的基于算子空间的公式发现算法, 并在算法研究的基础上设计实现基于算子空间的可视化公式发现系统, 该系统通过算子空间概念的引入, 简化了算子空间的规则, 同时引入导数规则、误差规则以及终止规则, 丰富了知识库内容。通过以上改进, 和 BACON 和 FDD 相比, 公式发现的形式更广, 复杂度更高。文章最后给出了应用实例以及公式发现的结果。 |

| 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. |
