回归与超越——漫议中国文学研究中的历史感问题

近几年来中国古典文学的研究呈现出两个鲜明的变化,即我们已经不满足于对浅层次艺术感的简单追求,而更加注重厚实的历史感;同时,我们也已经不满足于对某些现成理论的盲目套用,而更加注重文献的积累。由此,中国古典文学的研究呈现出向传统文献学回归的迹象。然而,从某种意义上说,传统文献学已经远远不能适用于新时代的需要。电子文献、出土文献、国外文献为传统文献学添加了许多新的内容,同时并为中国古典文学的研究超越传统文献提供了可能。

Perceptual learning of dot pattern

Dot pattern is a type of pattern defined by specific spatial relationship among some dots. As a compensation for concrete and meaningful visual stimuli, meaningless dot pattern can be used as stimuli in learning tasks. We performed an experiment for exploring the perceptual learning process of dot pattern against random-dot background. Participants were required to learn two types of dot patterns (9-dot and 11-dot). They were assigned to two groups: participants in Group 1 learned 9-dot pattern first and 11-dot pattern later, while those in Group 2 learned 11-dot pattern first and 9-dot pattern later. The results showed that participants could acquire the spatial relationship of dot pattern through perceptual learning in relatively short learning time. In comparison with 9-dot pattern, learning time of 11-dot pattern was slightly longer and its accuracy rate lower, but there was significant positive transfer effect from 11-dot pattern learning to 9-dot learning.     

企业危机预测与识别模型

针对当前大部分企业危机预警模型只能报警,不能预测的现状,提出一种基于指数平滑法与模式识别的预警模型。该方法首先对企业运营的单项特征指标进行预测,然后对预测结果模式识别分类,同时判断企业的危机状态。最后,用实例验证该模型的有效性。

基于XFP-tree的XML结构重构策略

基于海量XML文档查询速度已不能满足日益增长的信息关联和服务请求多样性的需求,本文提出一个重构XML结构的频繁向量选择增量模式树（XFP-tree）算法,该算法以XML键为基础,首先对XML结构进行向量矩阵处理,再通过投影频繁模式树实现对XML结构进行分裂、合并、更改与取消等优化措施,满足XML结构简洁性与查询多样性;结合投影和树结构技术,讨论XML键向量矩阵频繁项集的划分规则,而相应启发式策略的制定与支持度阈值的讨论有利于算法效率的提高。对比其它关联算法,一系列仿真实验表明所提出的算法具有一定的有效性及合理性,是重构XML结构的一种有效方法。     

A Fuzzy Neural Model for Face Recognition

Introduction1 Nowadays, biometric (e.g., face, finger print, iris, palm)identification is becoming more and more important [1] [2] and there are numerous commercial and law enforcement applications. Compared with other biometric identifications, face recognition has attracted more attention for its characteristics ofuser-friendly, intuitionistic and convenient. Much work hasbeen done on face recognition over the last 20 years. Generally speaking, face recognition is composed of three procedure…
