rough criterion
解釋
粗糙判據-
Taking this as a base, a concept of believability has been introduced, and the expression method of criterion of fuzzy critical hole expansion ratio under the upper and lower approximation set of rough set theory was advanced
在此基礎上，引進可信度的概念，提出模糊臨界空穴擴張比判據在粗糙集理論的上、下近似集下的表示方法。 -
This paper proposed some methods for finding out sure regions and ambiguous regions defined by lower and upper approximations in rough set theory. an applicable ending - criterion for semi - supervised back - propagation algorithm was proposed and a new rough classifier framework was studied, the assessment results show the effectiveness of the proposed criterion. a new classifier based on support vector machines was studied and applied
本文提出了幾種劃分樣本邊界區的方法:提出了一種應用於半監督bp演算法的實用結束判據，並根據粗糙集理論，研究了一種新的粗糙分類機制，取得良好的效果；應用支持向量機理論，構造分類器並劃分樣本邊界區；最後研究多個分類器集成的方法尋找樣本邊界區，同樣提高了暫態穩定評估的可靠性 -
Knowledge about the faults of a process control system is obtained automatically by rough set reduction. an entropy - based criterion is used to measure the uncertainty of it. methods of forward and backward fault diagnosis and how to build up decision tables for each fault source are given
利用粗糙集進行故障知識的發現，尋找系統各個故障源信號之間合理的邏輯關系，提出了一種構造邏輯故障樹的智能方法，並給出了相應的故障樹評價標準。 -
Conventional iec three ratio method and new iec ratio criterion are reduced according to the method of decision table in rough set theory respectively, simplified diagnosis rules are proposed. besides being identical with original iec method, the codes of conventional iec three ratio method are increased and bounds of new iec ratio criterion are augment by using this method, codes imperfectness of conventional iec three ratio method and code name absence of new iec ratio criterion are improved to some extent, scarcity of codes in conventional iec three ratio method is offseted, absolutization of sort and boundary in new iec ratio criterion is overcomed. this is important in practice for its flexibility and enhanced error tolerances
應用粗糙集理論中的決策表化簡的方法分別對常規iec三比值診斷表和iec新導則診斷表進行了化簡，得到了簡化的診斷規則，它們不但具有與常規iec三比值法和iec新導則完全相同的診斷分類能力，而且擴充了常規iec三比值表的編碼范圍和iec新導則的診斷范圍，在一定程度上改善了常規iec三比值表編碼缺損和iec新導則無對應代號的問題，彌補了常規iec三比值法編碼的不足，克服了iec新導則分類及邊界的絕對化，使得iec診斷法在實際診斷中更具靈活性、實用性和容錯性，提高了故障診斷能力。 -
First, method for initialization of wavelet basis in wavelet frames is proposed ; second, according to the data distribution, a modified method for rough selection of wavelet basis is given ; and the last, an adaptive projection algorithm combined with aic criterion is used to purify the wavelet basis, meanwhile finishing the parameters identification
首先在小波框架內提出一種小波基初始化方法；然後根據樣本的分佈特點，提出一種改進的小波基粗選方法；最後將自適應投影演算法與aic準則相結合，對小波基進行精選，同時完成網路參數的辨識。
