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。This paper simulates the effect of voltage fluctuation inspection through the tool of matlab. and proves the filters ' s stability. in the part of self - checkout, pi ( proportional integral ) control arithmetic is put forward to check the gain k and the calculated results show the method ' s effectiveness. then many comparements toward pst are done in different realization methods such as different interpolation points classification number and sample frequency. though simulation and calculation we can see the designed flicermeter can meet our country ' s standands
文中利用matlab對電壓波動的檢測效果進行了模擬;並對涉及到的濾波器的穩定性做了證明;在自校驗部分提出了將pi (比例、積分)演算法用於數字濾波器增益k值的確定,取得了不錯的效果;然後分別從取不同插值點、不同分級數和不同采樣頻率這幾個方面出發,對計算出的p _ ( st )值進行了比較。
