coordinate descent

基本解释

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数据集上的实验结果表明，算法能很快收敛，且分类精度优于并行下降算法和光滑支持向量机。
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.
并行下降方法应用于线性支持向量机时效率较低。
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.
利用块坐标下降法将求解联合正则化问题转化为交替求解三个独立优化问题，并分别提出了相应的求解方法。
