linear adj. 1.線的,直線的。 2.長度的。 3.【數(shù)學】一次的,線性的。 4.【動、植】線狀的;細長的。 5.由線條組成的,以線條為主的,強調(diào)線條的。 linear amplification 直線放大。 a linear equation 一次方程式。 a linear leaf 線形葉。 linear arts 線條藝術(shù)。
Some linear approaches reported recently without postprocessing to fir system identification are discussed . this paper improves the question of the promulgation of error due to estimating middle parameter frequently in other related methods , and presents a direct algorithm of estimating parameter without estimating middle coefficient . through proper mathematic means , for example , singular value decomposition ( svd ) or total - least squares solution ( tls ) , this algorithm smoothes the noise and improves effectively the estimation performance 和2階統(tǒng)計量相比,高階統(tǒng)計量不僅能夠有效抑制高斯有色噪聲的影響,而且能夠揭示隨機過程的相位特性,因此,高階統(tǒng)計量是解決非高斯、非最小相位、非因果系統(tǒng)和有色高斯噪聲環(huán)境的系統(tǒng)辨識和處理問題的重要分析工具。
Secondly , in respect bayes method is difficult in extracting features and in establishing statistical models , and the capability of no - linear approach is preferably for bp neural netw ork , the method ( bpbayes method ) to combine neural network with subjective bayesian was introduced . in this method , bp neural network was used to replace the experts of relevant domains for applying subjective bayes method 其次,考慮到bayes方法在特征建模上具有較大的難度,而bp神經(jīng)網(wǎng)絡(luò)具有較強的非線性逼近能力,為此我們將bp神經(jīng)網(wǎng)絡(luò)的輸出代替領(lǐng)域?qū)<业闹R經(jīng)驗,并用bp神經(jīng)網(wǎng)絡(luò)與主觀bayes方法結(jié)合起來的bpbayes方法對目標進行識別。
