 # Quickstart: Use a sample notebook from the Synapse Analytics gallery
 
 In this quickstart, you'll learn how to copy a sample machine learning notebook from the Synapse Analytics gallery into your workspace, modify it, and run it.
-The sample notebook ingests an Open Dataset of NYC Taxi trips and uses visualization to help you prepare the data. It then trains a model to predict whether there will be a tip on a given trip.
-
-This notebook demonstrates the basic steps used in creating a model: **data import**, **data prep**, **model training**, and **evaluation**. You can use this sample as a starting point for creating a model with your own data.

Post September 29, 2023, we will not be addressing any support tickets related to Spark 2.4. There will be no release pipeline in place for bug or security fixes for Spark 2.4. Utilizing Spark 2.4 post the support cutoff date is undertaken at one's own risk. We strongly discourage its continued use due to potential security and functionality concerns.

 ## Understand regression models
 
 *Regression models* predict numerical output values based on independent predictors. In regression, the objective is to help establish the relationship among those independent predictor variables by estimating how one variable affects the others.

 ### Azure Machine Learning automated ML
 [Azure Machine Learning automated ML](../../machine-learning/concept-automated-ml.md) (automated machine learning) helps automate the process of developing machine learning models. It allows data scientists, analysts, and developers to build ML models with high scale, efficiency, and productivity all while sustaining model quality. The components to run the Azure Machine Learning automated ML SDK is built directly into the Synapse Runtime.

 ### Open-source libraries
 Every Apache Spark pool in Azure Synapse Analytics comes with a set of pre-loaded and popular machine learning libraries.  Some of the relevant machine learning libraries that are included by default include:
