# ML inferencing

## Overview

For cutting-edge stream-based use cases, the incorporation of machine learning models is integral for next best action processing.

Out-of-the-box, Joule offers the capability to seamlessly deploy [JPMML](https://github.com/jpmml) models within a processing pipeline using a predictive processor.

Learn more about Joule's [ML inferencing architecture here](https://docs.fractalworks.io/joule/components/analytics/ml-inferencing/key-concepts).
