Risk Assessment M ode of Sale-Leaseback——Based on Fuzzy Analytic Hierarchy Process

Sale-leaseback is paid special focus on for its great application in China in recent years.By giving a detailed analysis,an analysis of the features of sale-leaseback and a study of the risks of it are given in this paper.Then a quantitative analysis of commercial real estate sale-leaseback is carried out.The scientific theoretical analysis is provided in this paper for risk assessment in commercial real estate sale-leaseback mode in China.An effective approach is put forward for sale-leaseback project evaluation and prevention of risk.A useful means is given to supervise commerciai real estate sale-leaseback mode for relevant departments and a certain contribution is made to a further sound development of commercial real estate sale-leaseback mode.

文档分类中的多特征最大值法及其改进方法

为在每个文档类别中选择更多的特征,解决至少一个特征法(ALOF)的特征不足问题,提出文档特征最大值法(MFT)和改进的文档特征最大值法(IMFT)。按照数据处理方式决定选择特征的数量,MFT法解析所有文档,确保训练集中每个文档都用最终特征矢量来表示,IMFT法只分析特征评估函数中特征值高的文档以选择较少的特征,减少选择不相关特征的概率。实验考虑3个文档分类数据库和3个评估函数,实验结果表明,与ALOF法和模糊关联聚类(FRC)法相比,提出的两种方法的F1测度更高,分类效果更好,评估函数对最终的分类结果具有重要影响,不同的特征数会左右最终结果。
