Examples
- Based on this kind of relations between the topological structures and the content distributions we study the web modelling , community identification and some related application problems in detail : first , after some existed characteristics of the web topology are verified , some new characteristics are discovered : the high clustering property in micro - topology ( high average gathering coefficient ) , the obvious mapping relation between the topological struture and the content in micro - level 、 linear irrelevant between the degree distribution of network nodes and the relative degree distribution of contents etc . then after analysis the topology of the complex network and the network modeling , the muti - scale determinism is proposed , especially for the information network a web evolvement model ( prcp model ) that fused the node authority and the node correlation is proposed . the model deduction , evolving learning verification and large scale experiment proof indicate that the model can explain the micro - topology centralizing phenomena , can imitate the mapping relation between the network connecting distribution and network content relative distribution and also can predict the mapping relation between the topology clustering and content clustering
本文在详细观察了web网络的拓扑结构特征以及拓扑结构与内容分布相互关系的基础上,以信息网络的物理连接拓扑结构与节点内容相关度分布之间的相互关系为主线,从网络特征、网络建模、社区分析及相关应用方面问题进行了深入细致地探讨:首先在验证了前人提出的web网络拓扑结构特征基础上,进一步发现了信息网络所具有的一些新特征: 1 )网络微观颗粒度的拓扑结构聚团与内容聚团存在明显的映射关系,具体包括节点之间的物理连边概率与节点之间的内容相关度成指数比例关系、节点形成三角形拓扑结构的概率与节点内容相关紧密程度之间同样具有一种指数比例关系; 2 )网络节点连接度整体分布与节点内容相关度整体分布是线性无关的; 3 )网络微观拓扑结构中的存在很强的集聚性(平均聚团系数很高) 。 - A multiwavelet - based code - division multiple - access ( mw - cdma ) scheme is presented based on the application of recent results in multiwavelet analysis filter , preprocessing and balancing to communications area . in mw - cdma . at first , the received signal is decomposed into the components in the orthogonal wavelet spaces , and then the multiuser demodulation is implemented in each wavelet space
多子波分析滤波器可将信号投影到线性无关的子空间上进行处理使得cdma中的特征码可以重复使用；时间上重叠的多个子波及其平移相互正交使得单位时间内可传输更多的pn码；优化设计的多子波时频特性使得频带的利用更为有效。 - In theory we require linear independence among variables used as inputting or outputting of bp net when we model the mineral processing plant with bp net . however it is always definite relativity in inputting variables or outputting variables in modeling of the mineral processing plant , which sets definite obstacle in high quality modeling
在应用bp网络建立选矿厂数学模型时，理论上要求作为bp网络的输入变量之间或输出变量之间应是线性无关的，而选矿厂数学建模中，输入变量之间或输出变量之间往往存在着一定的相关关系，这对建立高质量的模型设置了一定的障碍。
