threshold parameter meaning in Chinese
阈参数
Examples
- Then , on the basis of coupled wave equations , theoretically studies of opo threshold parameters and of the conversion efficiency and of linewidth control are presented . several principles of the optimum design for opo are discussed . the experimental investigations of noncritical phase matching
以耦合波方程为基础,分析和计算了光学参量振荡器的转换效率、抽运阈值、谱线宽度等特性,并在此基础上讨论了如何选择opo的各项参数。 - Then we focus on support vector machine and discuss its theory foundation , basic concepts , and crucial techniques of support vector machine . with these background , we further study several generally algorithms about support vector machine , especially for plait ' s smo ( sequential minimal optimization ) algorithm . points out an important source of inefficiency in platt ' s sequential minimal optimization ( smo ) algorithm that is caused by the use of a single value , then present an improved smo algorithm employed two threshold parameters
然后在研究了支持向量机的理论基础及基本概念和要解决的关键技术问题之后，又对当前各种比较通用的支持向量机训练算法进行了研究，比较了各种算法的优劣，尤其深入研究了platt等人的smo ( sequentialminimaloptimization )算法，指出这种smo算法低效的主要原因是采用了单一的阈值参数，然后参考keerthi等人的思想，提出了一种使用两个阈值参数的改进的smo算法，在uci数据集和我们的iga肾病数据集上的试验结果表明，这种改进的smo算法在训练速度上有一定的提高。
