+# Batch scoring of Spark machine learning models 
 
 ## Overview
 
-This scenario demonstrates batch scoring of a SPARK machine learning model on Azure Databricks. We use a predictive maintenance scenario where we classify machine sensor readings to classify a set of four machine components into _healthy_ or _unhealthy requiring maintenance_ states. The resulting supervised multi-class classifier model scores batches of new observations through a regularly scheduled Azure Databricks notebook jobs.

 The solution uses methods from the PySpark MLlib machine learning library but the scoring process can be generalized to use any Python or R model hosted on Azure Databricks to make real-time predictions.
