根据第一张ppt, 大的惩罚因子c会减少error,从而导致一个较窄的边界；反之相反
这样的话，也就是说SVM其实是在wider margin和lower error （=large penalty）之间寻找平衡。那么第二张ppt中" The SVM algorithm will choose a discriminant boundary that optimizes the trade-off between a wider margin and a lower total error penalty" 是否应该修改为"......the trade-off between a wider margin and a lower total error" 或者修改成"......the trade-off between a wider margin and a higher total error penalty"?
