摘要
文中首次提出具有动态特征的P-数据(Packet data)模型。P-数据模型通过改进P-集合(Packet sets)模型而得到,其由内P-数据(internal Packet data)与外P-数据(outer Packet data)共同构成。给出了P-数据模型与模型结构,得到了P-数据模型与它的属性合取范式扩展-萎缩生成定理,进而得到了P-数据推理(Packet data reasoning)模型与数据的智能获取定理;最后利用这些概念和结果,给出内P-数据智能获取与风险数据估计的应用。
P-data(Packet data)model possessing dynamic characteristics was proposed for the first time by improving P-sets(Packet sets)model in the paper.It is composed of internal P-set(internal Packet data)and outer P-set(outer Packet data),and it is obtained by improving packet sets.P-data model and model structure were given in this paper.The attribute conjunctive normal form of P-data model was got.And then,the model of P-data reasoning and the intelligent acquisition theoryem of data were obtained.Finally,these concepts and results were applied to internal packet data intelligent acquisition and risk estimations.
