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...
For performing multi-class classification, deep neural networks almost always employ a One-vs-All (OvA) classification scheme with as many output units as there are classes in a dataset. The problem of this approach is that each output unit requires a complex decision boundary to separate ...

所幸了解到一些单样本检测的算法,比如Isolation Forest,One-Class Classification,所以这篇文章就记录一下自己做的关于One-Class SVM 的笔记。 一,单分类算法简介 One Class Learning 比较经典的算法是One-Class-SVM,这个算法的思路非常简单,就是寻找一个超平面将样本中的正例圈出来,预测就是用这个超平面做决策,在圈...
One-class Classification with Deep Autoencoder Neural Networks for Author Verification in Internet Relay Chat-AICCSA 2019 在本文中,我们设计了一个自主的IRC监控系统,执行递归深度学习来分类消息的威胁级别,并开发了一种基于深度自编码神经网络的单类分类作者验证方法。实验结果表明,... ...
