模型设计的指导

  1. 修改采样的方案,通过每隔几轮的更新候选集合进行采样
    • 采样中当选择了(x_a, x_p)之后,如何确定选择的x_n是一个可以提升结果的点
  2. 细化case方案,重新定制损失函数,把损失函数可视化出来
  3. 设计x_a, x_p, x_n之间的矢量信息,求出夹角方向值,重新设计损失函数
  4. 通过增大的batch信息,将类内误差和类间误差添加到损失函数中去

问题以及解决?

  1. 所有的训练样本都是根据随机选择的,其中存在部分数据是很难被直接选择到的,导致10分类的分类器的分类性能下降
  2. 改进样本构造的方案,使得所有的样本都可以进入分类器进行训练
