Time series AnomalyDetection for Rust

Learn how it works

Build Status

Installation

Add this line to your application’s Cargo.toml under [dependencies]:

anomaly_detection = "0.3"

Getting Started

Detect anomalies in a time series

use anomaly_detection::AnomalyDetector;

let series = vec![
    5.0, 9.0, 2.0, 9.0, 0.0, 6.0, 3.0, 8.0, 5.0, 18.0,
    7.0, 8.0, 8.0, 0.0, 2.0, 15.0, 0.0, 5.0, 6.0, 7.0,
    3.0, 6.0, 1.0, 4.0, 4.0, 4.0, 30.0, 7.0, 5.0, 8.0
];
let period = 7; // number of observations in a single period

let res = AnomalyDetector::fit(&series, period).unwrap();

Get anomalies

res.anomalies();

Parameters

Set parameters

AnomalyDetector::params()
    .alpha(0.05)                    // level of statistical significance
    .max_anoms(0.1)                 // maximum number of anomalies as percent of data
    .direction(Direction::Both)     // Positive, Negative, or Both
    .verbose(false)                 // show progress
