coordinate descent

基本解釋

Experimental results on UCI dataset show Powell algorithm converges fast and its accuracy is higher than that of coordinate descent method and smooth SVM.
UCI數(shù)據(jù)集上的實驗結(jié)果表明，算法能很快收斂，且分類精度優(yōu)于并行下降算法和光滑支持向量機。
To improve the efficiency of coordinate descent method when it is applied to linear Support Vector Machine(SVM), Powell algorithm is applied to linear SVM.
并行下降方法應(yīng)用于線性支持向量機時效率較低。
Applying the block-coordinate descent method, the solution to compound regularizers is turned into dealing with three simple optimization problems alternatively, which can be solved respectively.
利用塊坐標(biāo)下降法將求解聯(lián)合正則化問題轉(zhuǎn)化為交替求解三個獨立優(yōu)化問題，并分別提出了相應(yīng)的求解方法。
