Overview

About

Maintained by Alaiñe IturriaCRAN page ↗GitHub ↗

Implements a set of online fault detectors for time-series, called: PEWMA see M. Carter et al. (2012) doi:10.1109/SSP.2012.6319708, SD-EWMA and TSSD-EWMA see H. Raza et al. (2015) doi:10.1016/j.patcog.2014.07.028, KNN-CAD see E. Burnaev et al. (2016) arXiv:1608.04585, KNN-LDCD see V. Ishimtsev et al. (2017) arXiv:1706.03412 and CAD-OSE see M. Smirnov (2018) https://github.com/smirmik/CAD. The first three algorithms belong to prediction-based techniques and the last three belong to window-based techniques. In addition, the SD-EWMA and PEWMA algorithms are algorithms designed to work in stationary environments, while the other four are algorithms designed to work in non-stationary environments.

Changes in 0.2.0

New Features
ReduceAnomalies is now available for the incremental processing
Minor improvements and fixes
Fixed the problems with CpSdEwma IpSdEwma OcpSdEwma and OipSdEwma that in some cases made return more results than rows in the dataset.
Fixed the error in GetWindowsLimits that gave an error when there were not anomalies in the dataset.
IpTsSdEwma and OipTsSdEwma implementation changed to its easier use.
Fixed an error in IpKnnCad.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/otsad/otsad_0.2.0.tar.gz"
pkgFile <- "otsad_0.2.0.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.2.0) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("alaineiturria/otsad")

Development version from alaineiturria/otsad. Installs pak first if it is not already available.
