    • 摘要: Eco-geographical regionalization involves dividing land into regions by considering both intra-regional consistency and interregional disparity and is based on the pattern of differentiation of eco-geographical elements.Owing to the complexity of the land surface,and the limitation of data and appropriate methods,regions in China have hitherto been mapped manually,meaning that the process of mapping was non-repeatable.To make the regionalization technique repeatable,this study aimed to extract and quantify the expert knowledge of regionalization using an automated method.The rough set method was adopted to extract rules of regionalization based on the existing eco-geographical regionalization map of China,as well as its corresponding meteorological and geological datasets.Then,the rules for regionalization were obtained hierarchically for each natural domain,each temperature zone,and each humidity region.Owing to differences in zonal differentiation,the rule extraction sequence for the eastern monsoon zone and Tibetan Alpine zone was temperature zone first followed by humidity region,with the reverse order being applied for the northwest arid/semi-arid zone.Results show that the extracted indicators were similar to those of the existing(expert-produced)regionalization scheme but more comprehensive.The primary indicator for defining temperature zones was the≥10°C growing season,and the secondary indicators were the January and July mean temperatures.The primary and secondary indicators for identifying humid regions were aridity index and precipitation,respectively.Eco-geographical regions were mapped over China using these rules and the gridded indicators.Both the temperature zones and humidity regions mapped by the rules show≥85%consistency with the existing regionalization,which is higher than values for mapping by the commonly used simplified method that uses the classification of one indicator.This study demonstrates that the proposed rough set method can establish eco-geographical regionalization that is quantitative and repeatable and able to dynamically updated.

    • 摘要: In order to grasp the different influence degree of various factors on the risk assessment of ground collapse in mined out area and a link between some factors, Rough set was adopted to evaluate the risk of ground collapse in mined out area.The theory has strong ability of data mining and knowledge discovery, and the core idea is knowledge reduction.That is, the theory can delete the attributes of the weak and the poor in the collection attributes, and then build the objective and reliable evaluation model.Taking the goaf surface subsidence information of the No.8 Mine of Pingdingshan Tian'an Coal Mining Corp.Ltd as example, combining with the field survey data, the goaf surface subsidence is evaluated.Evaluation result is close to the fact, therefore, it is feasible to evaluate the risk of goaf surface subsidence by using the Rough set.%为掌握各因素对采空区地面塌陷危险性评价的不同影响以及部分因素之间存在的联系,采用Rough set 理论对采空区地面塌陷危险性进行评价.该理论具有强大的数据挖掘和知识发现能力,把属性集合中的相关性弱以及重要性差的属性删除,从而能构建相对客观可靠的评价模型.以平煤八矿采空区地面塌陷为例,根据野外调查资料,对其采空区地面塌陷进行危险性评价,结果与实际调查情况基本吻合,表明Rough set理论在评价采空区地面塌陷危险性方面是适用的.

    • 摘要: Introduction to education is one of the basic courses in teacher education professional education, it covers a wide range of subjects. Thus, in order to practice the management teaching goals, the interdisciplinary developed mathematical tools are applied for the study. The participants of this study are students in course of introduction to education, and the research instruments applied are rough set, grey structural modeling (GSM), and matrix based-structural modeling (MSM). The purposes of this paper are: 1) To logically analyze educational datasets to practice the scientific traits in education;2) To benefit from directed hierarchical analysis to identify and propose action planning;3) To construct core-oriented educational structure as the criterion-reference for one-lesson-multiple-design and to provide the whole scope and visualized analysis with GSM and MSM.

    • 摘要: 健康是人们生活水平优良的重要指标,但是如何快速基于生理检测指标来评估其健康水平是智慧医学所关注的核心问题。由于各种生理检测指标之间具有冗余特性,因此对所分析的生理检测指标进行属性分析具有重要作用。Rough Set在知识挖掘方面具有很强的处理能力,本文依据Rough Set对Fuzzy数据的处理方法,提出一种Fuzzy Rough Set约简算法,该算法可以实现利用生理检测数据对健康快速评估。同时由于使用来Fuzzy理论,所以其结果更加适合人们的接受方式,更能体现数据本质的概率特性。对实际数据的仿真分析可以发现该算法在健康快速评估上具有高的识别准确度。

    • 摘要: An approach for key frame extraction based on Rough Set and SVM is introduced in the paper, which comprehensively utilises the DC coefficient of P frame and B frame and the motion features in compressed domain of MPEG video stream as well as the nor-compressed domain texture features. First, the method extracts the DC coefficient of P frame and B frame from video stream, and then it analyses the motion-activity, the motion-space distribution and the type of macro blocks. After the frame texture features are extracted, Rough Set is employed to conduct the reduction on them and SVM is used to sort and identify them afterwards. Experimental results show that the approach is effective in key frame identification.%综合利用MPEG视频流压缩域中P帧、B帧的DC系数和运动特征以及非压缩域纹理特征,提出一种基于RoughSVM的关键帧提取方法.该方法首先提取视频流中P帧、B帧的DC系数、分析运动活力性和运动空间分布和宏块类型、提取的纹理特征后,利用Rough Set对这些特征进行约减后,用SVM进行分类识别.实验表明,该方法能有效地识别关键帧.
