In a database the concept of an example might change along with time which is known as concept drift When the concept drift the classification model built by use of old data is unsuitable for classify new data Therefore concept drift has become a hot issue in data mining in recent years Although many algorithms had been proposed to resolve this problem they can not provide users with the reason of concept drift However a user might be very interested in such rules For example doctors want to find what makes disease change; researchers want to know the reason of the variety of the weather; and decision makers would like to understand why a customer's shopping habit change In this thesis we propose a Concept Drift Rule mining Tree called CDR-Tree to solve this problem CDR-Tree can not only find the rule of concept drift also build the prediction model for both old and new data at the same time

无论在大型资料库或现实生活中，同一资料样本的概念有可能会随著时间的递移而改变，也就是产生所谓的概念漂移。当样本发生概念漂移时，由旧有资料所建构的分类模组将不再适用於预测新获得的资料，因此，近年来概念漂移已成为资料探勘中一项热门的研究议题。虽然已有？多学者提出不同的技术来解决概念漂移的问题，但是这些方法都是利用修正或重建的方式来产生适合新资料的预测模组，并无法提供造成概念漂移的原因。然而对使用者而言，其感兴趣的可能正是这些引起概念漂移的规则，如医生可能想了解引起疾病变化的主因、学者会想要知道气候转变的规则、或是决策者想找出顾客购物习惯改变的因素等。因此，本论文提出概念漂移规则探勘树( Concept Drift Rule mining Tree )，简称CDR-Tree，来解决这个问题。CDR-Tree不但能探测出造成概念漂移的主要原因，亦能同时建立新旧资料的预测模组以供决策者运用使用。

The details d are following:1 Try to development social swimming sport, especially primary school and middle school swimming sport, so as to present wide base for talent selection.2 According to the geographical environments and swimming traditional of Vietnam, the key development area of competitive swimming is the following city , northern part of Vietnam:Ha Noi, Hai Phong, Quang Ninh, Thai Binh, Nam Dinh; mid-part of Vietnam:Thanh Hoa, Quang Binh, Da Nang, Binh Dinh; southern part of Vietnam: Ho Chi Minh, Long An, Vinh Long, Ben Tre. So it should establish national key swimming center in the above-mentioned city.3 Vietnamese organization concerning swimming sports should attach more attention to and organize specialist, experience coach to develop applied science research, so as to obtain more greater achievement in talent selection and scientific training.4 It is important for Vietnam to concentrate all of swimming specialist to organize national training committee, which is in charge of researching and establishing training program for every age stage, meanwhile it should direct swimming centers to implement this program.5 In order to promote the quality of swimming coach, national sports bureau and under-water sports association must establish'coach hierarchy system'.6 It is essential to improve the quality of sport team management. Currently, we must set up uniform scientific management goal and task, i.e. to improve the management ability of swimming coach.

相应的发展策略为：1努力发展群众性游泳运动，尤其是在儿童少年的各中小学学校的游泳运动，为科学选材提供更广泛的选材基础。2根据越南的地理环境和各地游泳转统在竞技游泳的重点发展地区的布局应该是在越南北部各省市：河内、海防、广宁、太平、南定，越南中部各省市：清华、广平、蚬港、评定，越南南部各省市：胡志明、龙安、永龙、槟蜘上面的各省市设为全国的重点游泳中心3越南游泳各层组织要重视和有计划地结合全国游泳学者、各项体育学者、有经验教练员开展应用科学研究，使得在选材工作和科学训练工作等获得更高的成效。4越南应集中全国的游泳专家、科学家成立国家训练委员会，负责研究和制定出各年龄组的科学训练大纲，同时指导全国各游泳中心统一使用。5为了能促进教练员更快的提高本身素质，国家体委和水平运动协会尽快制定&教练员等级&制度。6增强、提高运动员队的管理工作质量、目前要立即制定统一的科学管里目标和对教练员明确管理任务既提高教练员的管理能力。

No one knows who created the statue of the Aphrodite of Melos It is probably the work of the Greek artist Alexandros of Antioch This name was inscribed on the block of stone on the pedestal that was later lost, but this is doubted from scholars because it may not have been the corrected block with the Venus de Milo, so this had erased the attribution to Alexandros Some scholars had attributed the work of the statue to Praxiteles It is said that it was sculpted around the second century BC

没有人知道谁创作了雕像&米洛的维纳斯&。它可能是希腊雕刻家、安屈克亚的亚历山德罗斯的作品。因为在那块后来丢失的雕像底座上刻着这个名字，但是学者们对此表示怀疑，因为这可能不是真正的&米洛的维纳斯&的底座，这就使亚历山德罗斯是否是雕像的作者产生置疑。一些学者认为这尊雕像是普拉克西特利斯的作品。它据说是作于公元前2世纪左右。
