但是在单分类中,只有正常类一类样本参与训练,所有的样本来自同一个类别,让同一个类别的样本的表征距离尽可能远,这与深度单分类的思想冲突。在Deep one-class classification这篇论文中,通过最小化表征到中心的距离来学习表征(可能表达的意思是同一类的表征尽可能稠密)。 image.png image.png 表征的uniformity,对于对...
在one-calss classification中,边界应该全方位包围数据,我们定义一个对数据封闭的边界模型f(x;w):一个超球面。定义这个超球面的中心点为 a ,半径为R,我们需要这个超平面能够包含所有的训练数据,那么也就是说训练集的经验风险损失(empirical error)为0,那也就是说所有数据所有元素xi到超球面的中心a的距离应该严格小...

This is known as the one-class classification problem and it can be performed using either binary classifiers, by treating all other classes as the negative class, or one-class classifiers which only consider the class of interest. The key difference between these two approaches is in their ...

在soft-boundary Deep SVDD中,超球通过直接惩罚半径和落在球外的数据表示来收缩。与soft-boundary Deep SVDD 不同,One-Class Deep SVDD通过最小化所有数据表示到中心的平均距离来收缩球。惩罚所有数据点的平均距离,而不是允许一些点落在超球之外,这与one-class假设是一致的。
One-class classification tries to distinguish one class of objects from all other possible objects, by learning from a training set containing only the objects of that class. This is different from and more difficult than the traditional classification problem, which tries to distinguish between two...
