Interpreting H2O Isolation Forest Model
Understand how to build explainable anomaly detection models with H2O.
We'll cover the following...
Interpreting anomalies
There are two levels of interpretation:
Dataset level: High-level understanding of what segments of data are considered anomalous.
Record level: Understanding of why an individual record is considered anomalous.
We’ll start with the dataset level. Our goal is to gain an understanding of what segments of data are considered anomalous.
Dataset level
Once we have found the anomalies in our dataset, the next step is to understand why they are considered anomalies. To do this, we’ll train a decision tree. This will transform the unsupervised problem into a supervised one, where decision trees will help us uncover relationships between features and how they led us to the anomalies in our dataset.
The purpose of the decision tree ...
