[104] proposed an interesting alternative solution in anomaly detection for formed sheet metals. Instead of employing a CNN for direct prediction, they used a convolution autoencoder trained only on defect-free data, and the model identifies anomalies at the deploymen...

In this paper, we propose a new robust approach based on a convolutional autoencoder using fuzzy clustering. The proposed approach uses a parallel convolution operation to feature extraction, which makes it more efficient than the currently popular Transformer architecture. In the course...

(convolutional) autoencoders are particularly suited to it [32] and can be tailored efficiently to variations of the problem such as group anomaly detection [33]. The rebuilt image is not a cleaned image, but a compressed one, unlike in denoising autoencoders [34], but those cannot be ...

与其讨论异常检测(Anomaly Detection/Outlier Detection)，我今天想从一个更广的角度，也就是异常分析/...
7. MIDL 2018 Unsupervised Detection of Lesions in Brain MRI using constrained adversarial auto-encoders 使用的是AAE来学习建模正常数据分布。有时,对于在正常分布的的两个数据之间的距离,比一个正常和一个异常之间的距离还大,所以提出在隐空间也加一个约束。 暂时先写到这吧。 欢迎关注专栏其他分享: GAN整...
