K-Means聚类的多种距离计算方法的文本实验比较

针对文本类型数据的分类进行研究,用VSM模型和TF IDF技术对文本文件进行了数据样本抽取加权,得到文本相似度矩阵;采用不同样本距离计算方法和K-Means算法对数据进行了聚类实验,获得聚类结果并进行了分析和总结;基于实验结论,研究了不同距离计算方法之间的区别以及适用的数据类型。     

Experimental training of children with attention deficit/hyperactivity disorder

Attention-deficit/hyperactivity disorder （AD/HD） negativelly affects the cognitive and psychomotoric spheres of the pupil＇s social behavior and social adaptation. The review of many studies states that pupils with AD/HD achieve worse learning results because of insufficiently functioning cognitive processess, such as attention, （work） memory, thinking, problem solving, language, small- and large- scale motorics. Behavioral features, exhibited with AD/HD, include low-frustration tolerance, temper problems, persistence, emotional liability, depression, peer rejection, poor self-concept and poor self-esteem. Because of insufficiency of the cognitive processes, the difficulties of social behavior and social adaptation, pupils with AD/HD more often have a dysfunction of pupils＇ role that manifests by learning difficulties and behavior problems. The manifestation of the disorder in the younger school age in the context of children＇s school activities and roles actualizes the exceptional interest of the educational science in the analyzed phenomenon. The search and construction of effective means of socio-educational help for AD/HD primary class pupils should be associated with coordination and adaptation of different effective educational methodologies of different conceptual origin. In order to develop cognitive, psycho-motoric abilities and social behavior of the group of primary class pupils with AD/HD （N=22）, activities of supplementary education were organized after classes （their duration was 6 months）. During the forming experiment, original methodologies were constructed and national and foreign researchers＇ educational methodologies were adapted and tested in new, specific conditions （methods of fairy-tales, correction of cognitive behavior, graphical-logical tasks, games in the sport hall）. Even by relatively rare activities of supplementary education in a homogeneous group of children suffering from AD/HD positive changes of cognitive, psychomotoric sphere, social behavior and social adaptation were achieved.     

智能数字毫伏表在大学物理实验中的应用

智能数字毫伏表以单片机AT89S52为控制器,可对光学实验中的光强大小进行测量,并可对实验数据进行分析、处理,帮助验证相关实验原理。以光学单缝衍射实验为例,讨论数据的处理过程,并与理论值进行比较。本仪器操作简单,精度高,已应用在单缝衍射、偏振光、双缝干涉、杨氏模量测试等实验中。     

“说句玩笑话”“开个玩笑”及相关语篇现象

话语中独立使用的＂说句玩笑话＂＂开个玩笑＂,凝固性强,是语用标记语,简称为＂玩笑标记语＂。有语用标记功能及相应的篇章功能。提前引导或后置补充所标记话语的理解方向,消除其不合适性或误解可能,增强其内容和言语形式的可接受性,并突出自己的观点和态度。玩笑标记语与所标记话语构成语篇中的＂玩笑言语块＂,内部,形式衔接语义连贯;外部,作为一个言语整体在语篇中相对独立地存在,并与上下文取得形式和语义上的多重联系。有言语幽默效果。     

K_(2,r)-单路图谱半径的极限和上界

研究一种直径趋于无穷大的图类K2,r-单路图,利用图谱理论和高等数学求极限的方法,求得当点数n趋于无穷时,K2,r-单路图的谱半径有极限,并且求出了该极限值.进一步验证了该极限值即为K2,r-单路图的一个上界.     

关于费玛曲线xN+yN=1的K2群的一些注记

首先简单介绍了对于有理数域上光滑射影曲线的Beilinson猜想,然后应用椭圆簇的知识指出了存在于费玛曲线K₂群中的一个元素, 最后在费玛曲线X₃这个特殊情形下,将其L-函数与Eisenstein-Kronecker-Lerch级数明确地联系起来,从而验证了其L-函数满足的函数方程,以及它能在复平面上解析延拓的事实.
