Isolation Forest for anomaly detection

Project description

# iso_forest

This is a simple package implementation for the isolation forest method described (among other places) in this [paper](icdm08b.pdf) for detecting anomalies and outliers from a data point distribution.

## Extended isolation forest

For an extended version of this algorithm that produces more precise scoring maps please visit this repository


## Installation

pip install iso_forest

or directly from the Github repository

pip install git+

It supports python2 and python3

## Requirements

In addition, it also contains means to draw the trees created using the [igraph]( library.

## Use Examples

See these 2 notebooks examples on how to use it

  • [basics](demo_iforest.ipynb)
  • [tree visualization and anomaly PDFs](demo_vis_pdf.ipynb)

## Releases

### v1.0.3

  • Initial Release
