总异常分数由参数 β 表示为两个分数的加权和 S=β∗Sflow+(1−β)∗Srecon, 其中, Sflow=−pZ′(z′), Srecon=−SSIM(x,x′).
Anomaly detection refers to the task of finding unusual instances that stand out from the normal data. In several applications, these outliers or anomalous instances are of greater interest compared to the normal ones. Specifically in the case of industrial optical inspection and infrastructure asset ...

Anomaly Detection with Autoencoder Autoencoders are used to detect anomalies in a signal. The autoencoder is trained on data without anomalies. As a result, the learned network weights minimize the reconstruction error for load signals without arc faults. The statistics of the reconstruction error ...
In such cases, an unsupervised learning-based anomaly detection model (e.g. autoencoders) using only normal data may be applied in the initial phase of operation, and a supervised learning-based anomaly detection model with additional anomaly data may be applied once anomaly data have been ...

Despite numerous studies of deep autoencoders (AEs) for unsupervised anomaly detection, AEs still lack a way to express uncertainty in their predictions, crucial for ensuring safe and trustworthy machine learning systems in high-stake applications. Therefore, in this work, the formulation of Bayesian...
