argmax: 返回向量中最大元素索引 dot:向量点乘 matmul:矩阵乘法 read_matrix:读取矩阵文件 write_matrix:写入矩阵文件 calssify:调用以上函数连接各层 同时我们需要编写测试文件来测试程序的正确性,让我们用向量点乘举个例子 dot.s 功能:将两个向量点乘 输入: a0 (int*) 指向v0第一个元素的指针 a1 (int*) 指...

简介 Yuan-Hai Shao等人提出了一种改进的TWSVM,也称为孪生有界支持向量机(Twin bound Support vector Machine, TBSVM)。使用逐次超松驰(SOR)技术,针对优化问题,以提高训练过程的速度,还应用了结构风险最小化原则,在计算时间和分类精度方面,TBSVM比TWSVM更优秀。建议先读风险最小化() 线性TBSVM 与TWSVM一样,TB...

核心公式两个 $$ \begin{align} w^&=\sum_{i=1}^{N}\alpha_i^y_ix_i\ b^&=\color{red}y_j\color{black}-\sum_{i=1}^{N}\alpha_i^y_i(x_i\cdot \color{red}x_j\color{black}) \end{align} $$ 这里面比较重要的是$b^$的公式的理解,通过$\arg\max \alpha^$实现,因为支持...
