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 ...
利用Autoencoder进行无监督异常检测(Python) SofaSofa.io AutoEncoder(一):AutoEncoder可视化介绍 王斐发表于炼丹手册 AutoEncoder, VAE and AAE 1、AutoEncoder自编码器是一种特殊的神经网络架构,通过无监督方式训练模型来获取 输入数据在低维空间的隐式表达(隐变量)。训练时,自编码器分为编码器和解码器两部分,训练...
AutoEncoder是深度学习的一个重要内容,并且非常有意思,神经网络通过大量数据集,进行end-to-end的训练,不断提高其准确率,而AutoEncoder通过设计encode和decode过程使输入和输出越来越接近,是一种无监督学习过程,可以被应用于降维(dimensionality reduction)和异常值检测(anomaly detection),包含卷积层构筑的自编码器可被应用...
