Design and Implementation of Three Certificate Together Integrating System for Heilongjiang Taxation [PDF]

open access: yes, 2016
摘要 近几年来,随着计算机信息化技术在各部门中的广泛应用,在部门与部门之间形成了各自独立的数据采集、处理和分析利用的应用系统,如工商、国税、质监等,但这些系统之间不能互联互通,形成了各自的“信息孤岛”,如何消除这些“信息孤岛”,建立一个开放、集成、交互式的应用系统是当前各部门间信息化建设的迫切需要。为此,本论文将数据库交互技术与国税系统业务实际相结合进行了三证合一软件平台的研究,对于各部门间信息化水平的提高和大数据时代税务信息化建设有着重要的推动作用 ...

Design and Development of a Student Status Management System for Vocational School Based on Data Mining [PDF]

open access: yes, 2015
计算机技术快速发展,对学校的教学管理带来深刻的影响。一个好的管理信息系统就能够合理地管理以往难以处理的大量数据。 但是,管理信息系统的功能仍然不够。数据中隐含的规则难以被利用。这些潜在的规则对学校的管理、招生工作的进行都有重大意义。 本文主要是在统计、整理某职校的学生学籍数据的基础上,设计基于数据挖掘的学生学籍管理分析系统,通过在招生、成绩等数据模型中的具体挖掘实践,得到有启发性的信息。 本文试图帮助教师们做好教学工作,也可以帮助学校教学管理部门更好地对学生进行培养。主要的工作包括: (1)对学生学籍 ...

Bootstrap样本大数据模型和分布式集成学习方法

open access: yes大数据
传统Bootstrap抽样和Bagging集成学习通常以串行方式实现,计算效率低,且存在样本不可重用、扩展性差等问题,不适合高效的大规模Bagging集成学习。从大数据分布式计算的思维入手,提出新的Bootstrap样本划分(BSP)大数据模型和分布式集成学习方法。BSP数据模型通过分布式生成算法将训练数据表达成分布式Bootstrap样本集的集合,存储成HDFS分布式数据文件,为后续的分布式集成学习提供数据支持。分布式集成学习方法从BSP数据模型中随机选取多个BSP数据块,读入集群各个节点的虚拟机 ...
