As a data scientist, I've often found myself spending hours manually selecting algorithms, tweaking hyperparameters, and training models.

But what if I told you there's a way to automate most of these tasks? Enter Azure Machine Learning's automated machine learning (AutoML) feature.

In this article, we'll walk you through a step-by-step guide on how to use Azure AutoML to streamline your machine learning workflows.

What is Azure AutoML?

Azure AutoML is a cloud-based automated machine-learning feature that enables you to build, train, and deploy machine-learning models without extensive coding knowledge. It supports a variety of machine learning tasks, including classification, regression, and forecasting.

Requirements to Get Started

• Azure subscription

• Azure Machine Learning workspace

• Basic understanding of machine learning concepts

• Data in Azure-supported formats (e.g., CSV, JSON)

Step 1: Create a New Machine Learning Workspace

• Log in to the Azure portal.

• Click on "Create a resource" in the top left corner.

• Search for "Machine Learning" in the search bar.

• Click "Create"

• Fill in the required details:

  • Workspace name

  • Subscription

  • Resource group

  • Location

• Click "Review + Create"

• Wait for the workspace to be created

Step 2: Create a New AutoML Experiment

• Navigate to your Machine Learning workspace.

• Click on "Launch Studio" in the left menu.

• Click on "Automated ML" on the left tab.

• Click on the "New automated ML job" button.

Provide your dataset

• Specify a dataset by uploading a file or importing it from another source (Like your local drive).

• Ensure your dataset is "tidy" (each row is one observation, each column is one variable, each cell is one value)

• Define the schema of your data by selecting which columns to use to create the model

Step 3: Configure the Auto ML Job

Set up a new compute resource by selecting "New" and creating a compute cluster with low priority.

• Add other necessary details to create a cluster. This will provide the necessary processing power for your Auto ML job.

• Choose the machine learning task that best suits your needs:

  • Regression: Predict a continuous numeric variable, such as a price or a quantity.

  • Classification: Assign an observation to one of several classes, such as spam or non-spam emails.

  • Time Series: Predict multiple steps into the future, such as forecasting sales or weather patterns.

• Review your settings to ensure everything is correct, then submit the Auto ML job by clicking "Finish". This will start the automated machine-learning process.

Step 4: Let Auto ML find the best model

• Wait for Auto ML to do quality checks on your data and prompt you if there are any major problems

• Auto ML will try to find the best model that can compute your target variable given all other variables.

Step 5: Deploy a model

• Stop the compute resource

• Explore the different models generated by Auto ML and select the best-performing one

• Deploy the model as a real-time web service or batch deployment

Step 6: Consume a model

• Find the URL and demo scripts to get predictions from your model under Endpoints

• Integrate the model into your reports or dashboards using online prediction or batch prediction

Step 7: Clean up resources

• Delete the resources you created to avoid incurring any costs
