In coal mining operations, the stable operation of hydraulic supports is crucial for ensuring mine safety. However, the nonlinear, non-stationary characteristics and noise interference in hydraulic support pres
Then, in Sections 3.2.2.1 and 3.2.2.2, we detail the two main methods utilized in this paper that employ deep autoencoders for anomaly detection. 3.2.1 Deep Autoencoders An autoencoder is a unique variant of feed-forward neural networks aiming to have the output closely mirror the input....
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...
其中R 是一个 1 × 1 的可逆卷积,它反转通道的顺序,Ψ(·)是 Softplus激活函数\frac{1}{ β} * log(1 + exp(β ∗ ·))其中β = 0.5,sglobal 和 tglobal 正在学习actnorm步骤中scale和bias对应的参数,⊙为point-wise product。对于耦合层,我们通过通道将输入 x 分成两个组合(x1, x2)^{⊤},...

In this paper, we focus on data-driven anomaly detection and experimentally compare several topologies of deep autoencoders for detecting anomalies in the electrical energy consumption of buildings. We consider both plain and variational autoencoders, with different mixtures of recurrent, convolutional,...

大家好,第一篇文章是来自ACMMM,作者团队为阿里巴巴。选择这篇的原因是觉得这篇文章简单有效,与我之前很多想法都不谋而合。 1. 什么是异常行为检测? 就目前而言,视频中的异常行为检测就是给定一部分只包含正常行为的样本片段,在此基础上构造可行算法,将测试样本中异常行为检测出来。这是一种无监督问题。 目前常见的...
