This paper summarized a system feature set for transient stability classification, several methods for analyzing the separability of input space of transient stability classification are discussed, tabu search - ing technique is employed to select an effective set of features from a large initial features set. the classification test shows that the presented method works very well for feature selection. fisher linear recognition is employed to cut down the training sample set, the computation burden of the ann training is alleviated very much, so the convergence performance is improved
本文總結提出了一組用於穩定分類的系統特徵，研究了幾種暫態穩定分類輸入空間可分性分析的方法，並利用tabu搜索技術從一個維數較大的特徵集中選擇出一組有效特徵，取得了良好的效果；研究提出了利用fisher線性識別技術壓縮訓練樣本集的方法，大大減輕了ann的訓練負擔，提高了ann收斂的性能。 -

Our results showed as follows : 1 ) the spl and rsal polymorphisms of the collagen type 1 alpha 1 ( col1 al ) gene, the - 174g / c promoter polymorphism of the interleukin - 6 ( il - 6 ) gene, the asn363ser polymorphism of the glucocorticoid receptor ( gr ) gene, and the t ? c polymorphism in intron 5 of the transforming growth factor pi ( tgf - p ! ) gene are absent or too rare in chinese. compared the polymorphisms of these five markers with other populations using % 2 test and fisher ' s exact two - tailed test, significant differences of allele and genotype frequency distributions were observed at these polymorphisms ( p < 0. 001 )
結果表明： 1 ）白介素6 （ il ? 6 ）基因的? 174g c多態性、型膠原蛋白_ 1 （ col1a1 ）基因的sp1和rsa多態性、轉化生長因子_ （ tgf - _ 1 ）基因的內含子5t c多態性和糖皮質激素受體（ gr ）基因的asn363ser的多態性在中國人群中均未發現或者多態性很低； x ~ 2檢測和fisher精確（雙尾）檢驗比較這些多態性的頻率，發現在中國人群與其它種群或人群中，等位基因和基因型存在顯著的差異（ p 0 . 001 ） 。 -
In training process, we use kernel - based fisher discrimination analysis ( kfda ) method to train the input sample vectors. the method has been used in face recognition and has been demonstrated better recognition capability than other methods ( pca, kpca, svm ). we calculate the optimal subspace wopt and project the sample gait sequences to wopt, then get the tracks of the sequences, calculate the track centroid and calculate the exemplar projection centroid of the sequences in the same class, and the exemplar projection centroid represents the class template. to test the class of a gait sequence, we also project the test sequence to the eigenspace, and calculate the track centroid, then calculate the euclidean distance of the test sequence tracking centroid with the sample sequences ’ exemplar projection centroids. and the class which the test sequence belongs to is the one that the sample sequence which the euclidean distance is shortest belongs to
該方法在人臉識別的研究中已有採用並在同樣測試條件下取得比其他識別方法更好的識別性能。採用kfda方法取得最優特徵空間wopt ，把步態樣本序列映射到wopt中，取得樣本序列在特徵空間中的軌跡，計算軌跡質心，把同類樣本序列的軌跡質心進行平均求得該類的標本投影軌跡質心，作為該類的模板。在識別時，將測試序列也投影到特徵空間中，取得序列軌跡質心，對測試序列軌跡質心與樣本的標本投影軌跡質心計算它們的歐氏距離。 -
