By mapping input data into a high dimensional characteristic space in which an optimal separating hyperplane is built , svm presents a lot of advantages for resolving the small samples , nonlinear and high dimensional pattern recognition , as well as other machine - learning problems such as function fitting Svm的基本思想是通過非線性變換將輸入空間變換到一個高維空間,然后在這個新的空間中求取最優(yōu)分類超平面。它在解決小樣本、非線性及高維模式識別問題中表現(xiàn)出許多特有的優(yōu)勢,并能夠推廣應(yīng)用到函數(shù)擬合等其他機(jī)器學(xué)習(xí)問題中。
The fourier transform infrared ( ftir ) spectrum is an effective technology for studying the hydrogen content ( ch ) and the silicon - hydrogen bonding configuration ( si - hn ) of hudrogenated amorphous silicon ( a - si : h ) films . in the paper , ch and si - hn of a - si : h films , fabricated at different ratio of h2 / sih4 by microwave electron cyclotron resonance plasma chemical vapor ( wmecr cvd ) method , have been obtained by analyzing their ftir spectra that are treated by baseline fitting and gaussian function fitting . the effects of ratio of h2 / sih4 on ch and si - hn are studied Fourier紅外透射( ftir )譜是研究氫化非晶硅( a - si : h )薄膜中氫含量( c _ h )及硅-氫鍵合模式( si - h _ n )最有效的手段,對于微波等離子體化學(xué)氣相沉積( mwecrcvd )方法在不同h _ 2 sih _ 4稀釋比下制備出的氫化非晶硅薄膜,我們通過紅外透射光譜的基線擬合、高斯擬合分析,得出了薄膜中的氫含量,硅氫鍵合方式及其組分,并分析了這些參數(shù)隨h _ 2 sih _ 4稀釋比變化的規(guī)律。
