Use the following procedure to remove the profit margin sample. 使用以下过程删除利润率示例。
Secondly pointed out that the reason of analysis margin is mainly the staining of sample caused by environment. 指出了分析空白产生的原因主要由环境、试剂、器。
When the margin support vector set was empty, some sample was added into this set by updating the model bias, so that the training algorithm could run again. 边缘支持向量集合为空时,修改模型的偏值项使样本进入该集合,训练算法得以继续运行;
Results: Non-inferiority margin δ is define as 20% of the sample rate of control group, a one-side u test was carried out; 结果:非劣效性界值δ取对照组各率的20%,进行单侧u检验;
Through maximalizing the margin, we can obtain the optimal projection vector, and avoid the small sample size problem due to singularity of the within-class scatter. 通过极大化该边界获得最优投影向量,同时避免因类内离散度矩阵奇异导致的小样本问题。
Measure the minimum length of resection margin in each sample and record the number, size and position of lymph node dissected. 测量每例肝癌标本的最小切缘,记录清扫淋巴结数量、大小和位置。
The main work of this paper can be divided into three parts. Firstly, this paper researches on the support vector data description proposed on the basis of the SVM and minimum bounding sphere theory which including hard margin, soft margin and negative class data sample method. 论文主要工作有以下三个个方面。首先,论文研究了在支持向量机及最小包围球理论基础上发展起来的支持向量数据描述算法,包括硬间隔、软间隔及带负类样本的SVDD方法。
