Based on them, this paper proposes evaluation indexof fund performance from the aspect of finance, investor and interiormanagement. Considering the limitation of data envelopment analysis approach usedto evaluate fund performance, such as conventional DEA models can not considerinputs and outputs of evaluation units simultaneously, and an input-oriented DEAmodel and output-oriented DEA model often produce different evaluation results,this paper proposes a general form of DEA model which is input- andoutput-oriented by using multi-objective optimization and fuzzy set theory. Sincethe general form of DEA model can be transformed into a conventional input oroutput oriented DEA model by using special membership functions, it can beseemed as a nature extense of conventional DEA models, and a conventionalmodel can be regarded as a special case of DEA mdoel with general form.
针对现有基金绩效评价方法中较具优越性的数据包络分析方法的不足,如传统DEA模型不能同时综合考虑评价单元的输入和输出,以及分别采用面向输入和面向输出DEA模型评价基金绩效时,常常出现不一致的评价结果等,本文以多目标优化与模糊集合理论为工具,提出了一种能够同时面向输入和输出的DEA一般形式模型,并通过选择一些特殊的模糊集合隶属函数,使得这种DEA一般形式模型成为传统DEA模型的自然推广,而传统DEA模型是该模型的特殊形式。

This method uses what Professor Salton has proposed as the vector spacial model to express text as an invisible vector in hyperspherical space.It makes use of certain pre-disposal methods (reduce the dimensions,clustering thesaurus,filtering out old-fashioned words) to reduce the dimensions.It usescosines to measure the degree of similaritybetween texts and uses the total similarity as the target convergence vector.It produces clustered results by using restricted iteratives to achieve partial perfection.
该算法用Salton教授提出的向量空间模型把文本表示成不可视的超球向量空间的一个向量,采用一定的预处理手段(降维、同义词归并、停用词过滤)完成维数约减,使用余弦相似度度量文本之间的相似度,并选择总凝聚度作为目标收敛函数,通过有限次的迭代达到局部最优,输出聚类结果。

The creative point of this dissertation consists firstly in that monochromatic stimuli instead of combined spectral power distribution were used as visual object, and spectral luminous efficacy curves were drawn from the performance-based method; Comparison between performance-based method and brightness-matching method was then done and therefore connection between these two methods was developed; One more creative point is that the analysis based on the theory of neurophysiology and psychophysics leads to the conclusion that contribution of the colour channel during visual information processing is reflected from performance-based method, which should be considered when CIE develops the new mesopic photometry system.
论文的新颖之处在于实验中使用了单色光谱代替复合谱或物体色作为视觉目标,在分析中间视觉状态下视觉功能的光谱响应特性的基础上反推了人眼的光谱光视效率函数;论文更进一步验证了基于视觉功能法和传统的视亮度匹配法之间的联系,在两种方法之间构造了一座桥梁,为基于视觉功能法的使用初步建立了理论依据;同时论文创新地采用心理物理学的方法进行实验和结合物理学和视神经生理学的知识对实验结果进行分析,从而从视觉信息处理的神经机制层面证明了基于视觉功能法获得的结果包含了视觉颜色通道效应,并对CIE在建立新的中间视觉光度学系统时要充分考虑这一视觉颜色通道的影响提出了建议。

This can occur in cases where the target API is shorter than 5 bytes (CALL and JMP are each 5 bytes long). Another issue is the need to constantly switch between the patched and "unpatched" versions of the intercepted function.
