How to Use Azure Machine Learning Designer
1. Creating a New Pipeline
To start using Azure Machine Learning Designer, you need to create a new pipeline. Here’s a step-by-step guide:
- Access Azure Machine Learning Studio: Navigate to the Azure Machine Learning Studio and select “Designer” from the left-hand menu.
- Create a New Pipeline: Click on “+ New Pipeline” to start a new project.
- Choose a Template (Optional): You can either start from scratch or select a pre-built template that suits your needs.
2. Building the Workflow
Once the pipeline is created, you can begin constructing your workflow:
- Add Modules: Drag and drop modules from the left-hand pane into the canvas. These modules include data input, data cleaning, model training, and evaluation components.
- Configure Modules: Click on each module to configure its settings. For example, you can specify the dataset to be used or set parameters for the machine learning algorithm.
- Connect Modules: Connect the modules by dragging a line from one to another. This defines the flow of data through the pipeline.
3. Training the Model
To train the model:
- Select a Training Module: Add a training module, such as a classification or regression algorithm, to your pipeline.
- Configure Training Parameters: Set the parameters for the chosen algorithm, including hyperparameters and training options.
- Run the Pipeline: Click the “Run” button to start the training process. The designer will execute the workflow and train the model based on the specified settings.
4. Evaluating the Model
After training, you need to evaluate the model’s performance:
- Add an Evaluation Module: Drag an evaluation module to the canvas.
- Connect the Model: Link the trained model to the evaluation module.
- Review Results: Run the pipeline and review the evaluation metrics to assess the model’s accuracy, precision, recall, and other performance indicators.
5. Deploying the Model
Once satisfied with the model, you can deploy it:
- Add a Deployment Module: Include a module for deployment in your pipeline.
- Configure Deployment Settings: Set the parameters for how and where the model will be deployed.
- Publish the Model: Complete the deployment process to make the model available for use in production environments.
