  1. Feature extraction through 2 - order polynomial fit of the descending part of the response curve made possible a timesaving measurement process. the performances of two pattern recognition algorithms, namely principal component analysis ( pca ) and linear discriminant analysis ( lda ) in practical problems were discussed. artificial neural network ( ann ) was utilized with back - propagation algorithm ( bpa ), and the combination of pca / lda with ann improved the identification performance of the system

    基於對模式識別系統的深入研究,提出了從響應階段數據提取特徵的方法,節省了測試所需時間;比較了主成分分析法( principalcomponentanalysis , pca )與線性判別式法( lineardiscriminantanalysis , lda )兩種模式識別方法在實際應用中的不同結果,分析了原因;設計了採用誤差反傳演算法back - propagationalgorithm , bpa )的前向人工神經網路( artificialneuralnetwork , ann ) ,並指出其應用中存在的問題,提出了改進建議;利用pca lda與ann相結合的方法改善了系統的識別性能。
