One class classification is a machine learning approach different from the traditional pattern recognition approach where two or more class samples are required. however in some real - life cases, we can hardly, even not, get the samples of some classes, or have to pay costly price to obtain the so - needed samples, such as in the case of machinery malfunction. and while in other cases, the sizes of samples among classes are imbalance, such as medical diagnosis
單類分類器是不同於傳統模式識別的一種機器學習方法,傳統模式識別方法一般需要多個類別的樣本(至少兩個) ,而在有些場合中,幾乎無法獲取多類的樣本,或者獲取其樣本所需花費的代價非常高,比如:機器故障中我們不可能為了去獲得故障樣本而讓機器特意產生故障;又有些場合的類別樣本個數嚴重不平衡,比如醫學上的疾病特徵與非疾病特徵的比例是嚴重不平衡的。Applying the basic theories of spatial data mining and geomorphology, taking the loess plateau of north shaanxi province, china as the research area, this dissertation explored the theories and systematic structures of geomorphologic data mining and acknowledge discovery from dems, ascertained the systematic structures of topographic factors and synthetic topographic acknowledge, as well as systemically summarized mining algorithms from dems. the author pa id more attention also to analyze the principle and algorithm of flow length, curvature, relief, the earth ' s surface incision and gully density. in this research, the elementary constitutes and mining algorithms of regional character acknowledge in the loess plateau were probed

( 2 ) the var risk management model can provide the timely and comprehensive risk information for the top risk manager, so it is very helpful to the improvement of total risk management efficiency. ( 3 ) based on the var model, the raroc performance valuation approach can reflect the real performance of the portfolio manager and provide the coherent standard for the allocation of risk limitation and the construction of the incentive compatibility constraint mechanism in the financial instiutions
通過研究分析,本文主要得出如下結論: ( 1 )傳統的markowitz均值? ?方差模型僅僅是在資產組合收益率正態分佈假設條件下基於var風險管理模型進行資產組合選擇的特例,與均值? ?方差模型中的方差風險度量方法相比, var風險管理模型能夠更全面、更貼切地衡量資產組合的風險,且基於此模型能夠更有效地進行資產配置決策; ( 2 ) var風險管理模型能夠滿足更高層次風險管理者對風險信息的需求,有助於整體風險管理效率的提高; ( 3 )基於var風險管理模型的raroc績效評價能夠反映資產組合管理人的真實業績,從而為金融機構風險限額的分配和激勵約束機制的制定提供統一的標準; ( 4 )國內證券市場資產組合收益率服從正態分佈的假設明顯不成立,實證檢驗表明基於資產組合收益率正態分佈假設條件下的方差? ?協方差模型對國內資產組合風險的預測存在較大的偏差,由於文中證明在收益率正態分佈假設條件下基於方差? ?協方差模型進行資產組合選擇的結果等價于markowitz的均值? ?方差模型,因此,均值? ?方差模型對國內資產組合風險的預測同樣會存在著較大的偏差,而半參數var風險管理模型則能夠取得較好的預測衡量效果; ( 5 ) var風險管理模型符合未來金融風險管理的發展趨勢,基於var風險管理模型建立內容提要風險限額內控體系、風險信息披露體系和業績評價體系,並進行金融監管,將有助於國內金融機構內部風險管理方法和外部監管技術跟上國際金融風險管理的發展潮流。Multi - stage stratified cluster sampling with proportional allocation was used to determine the study population, which was equal to approximately 0. 5 % of all students in that age group in taiwan
