One-class learningImage classificationProbabilistic modelDeep neural networkOne-class learning has many application potentials in novelty, anomaly, and outlier detection systems. It aims to distinguish both positive and negative samples with a model trained via only positive samples or one-class annotated...

2.--type : Type of CNN : oneclass / feature. When oneclass is used classification is done using DOC. Otherwise pre-trained deep features are used. 3.--output : Output directory name. 4.--dataset : Specify the path to the training dataset. Eg: data/abnormal/ ...
An alternative class of classification algorithms that have emerged in recent years are Deep Belief Nets (DBNs), which have been proposed as a multi-class classifier and dimensionality reduction tool [18], [19], [20]. DBNs are multi-layer generative models that learn one layer of features at...
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,... 查看原文 [coursera/...
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...
2. Formulation We analyze the popular one class hinge loss (Schölkopf et al., 2001), and extend it under universum settings to propose the Deep One Class Classification using Contradictions DOC3 algorithm. Further, our proposed 'learning from contradiction' is a generic learning setting and ...

One-class classification refers to approaches of learning using data from a single class only. In this paper, we propose a deep learning one-class classification method suitable for multimodal data, which relies on two convolutional autoencoders jointly trained to reconstruct the positive input data...
