Fˉ-残缺数据是由Fˉ-数据(x)Fˉ与损失数据(x)-构成的数据对((x)Fˉ,(x)-),((x)Fˉ,(x)-)具有内-动态特性,应用于一类具有数据元减少特征的信息系统。基于Fˉ-残缺数据可视化问题,应用Fˉ-残缺数据提出Fˉ-残缺数据圆概念,讨论Fˉ-残缺数据辨识与恢复的几何方法。给出Fˉ-残缺数据圆位置关系定理,Fˉ-残缺数据的Fˉ-残缺数据圆辨识定理与辨识准则;给出Fˉ-残缺数据的Fˉ-残缺数据圆恢复定理,并给出应用。Fˉ-残缺数据圆是由数据圆OFˉ,O-构成的数据圆对(OFˉ,O-),Fˉ-残缺数据圆为研究Fˉ-残缺数据提供了一种几何方法。
The F-incomplete data are data pairs ((x) Fˉ, (x) -), ((x) Fˉ, (x) -) consisting of the Fˉ-data (x) F and the loss data (x) Dynamic characteristics, used in a class of information elements with reduced data elements. Based on the visualization of Fˉ-incomplete data, the Fˉ-incomplete data circular concept was proposed by applying Fˉ-incomplete data and the geometrical method of identifying and recovering Fˉ-incomplete data was discussed. The rounding theorem and identification criteria for Fˉ-incomplete data of Fˉ-incomplete data are given. The F-incomplete data circular recovery theorem for Fˉ-incomplete data is given and applied. F ˉ-incomplete data circle is a data circle OFˉ, O- data circle (OFˉ, O -), Fˉ-incomplete data circle for the study of F ˉ-incomplete data provides a geometric method.
