A signal representative of time series data associated with network traffic is received at a processor for analysis. A data segmentation algorithm and an anomaly detection algorithm are applied in series to the received data. The segmentation algorithm detects regime shifts in the data. Data between...

SR in time series 微软主要提出和比较了SR和SR+CNN方法在时序数据异常检测上的效果,其中SR算法唯一的差别是输入变成了时序数据。 如下图所示,得到了saliency map之后,很容易利用一个简单的规则来注释异常点。可以采用一个简单的阈值 τ\tauτ 来注释异常点。

时序预测的基本假设就是”平稳时间序列假设(stationary time series hypothesis)“,所谓平稳时间序列假设是指下列3种统计特性随时间变化相对恒定: 线性均值 常数方差 自相关 相对的,非平稳序列是统计特性随时间变化的序列。在开始任何预测建模之前,都有必要验证这些统计属性是否是常量,接下来我们逐一讨论。

马东什么:单序列单变量时序异常检测——revisiting time series outlier detection(更新于20211201)84 赞同 · 5 评论文章 前面的基础部分没啥好讲的,见上即可。 这篇文章是关于单变量时间序列异常检测的,但是不对单序列和多序列问题进行区分,所以arma这类常规的统计学预测模型直接对每个序列构建一个,真是简单暴力。
