Isolation Forest for anomaly detection

# 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
