By using the universal approximation property of neural networks ( nn ) , a three - layer feedforward neural networks is embedded into the framework of standard pls ( partial least squares ) modeling method resulting in a nonlinear pls - nn model 提出將線性pls模型通過神經(jīng)網(wǎng)絡(luò)逼近策略拓展到非線性的pls - nn方法,構(gòu)造了基于梯度下降算法的神經(jīng)網(wǎng)絡(luò)權(quán)值矩陣學(xué)習(xí)規(guī)則。
During this annual conference to be held between june 23 and 25 , the heads of customs administrations from 166 wco members worldwide will consider , among other issues , the adoption of the " framework of standards to secure and facilitate global trade " ( fos ) developed by the wco s high level strategic group 于六月二十三日至二十五日年會舉行期間,來自世界各地的166個世界海關(guān)組織成員的海關(guān)首腦將討論多個事項,其中包括采納一套由世界海關(guān)組織高層策略組發(fā)展的保障及利便國際貿(mào)易標準。
