Question
What does automated machine learning in Azure Machine Learning enable you to do?
A. Automatically deploy new versions of a model as they’re trained
B. Automatically provision Azure Machine Learning workspaces for new data scientists in an organization
C. Automatically run multiple training jobs using different algorithms and parameters to find the best model
Answer
C. Automatically run multiple training jobs using different algorithms and parameters to find the best model
Explanation
Automated machine learning runs multiple training jobs, varying algorithms and parameters, to find the best model for your data.
Automated machine learning (AutoML) in Azure Machine Learning enables you to do C. Automatically run multiple training jobs using different algorithms and parameters to find the best model.
AutoML is a process that automates the time-consuming, iterative tasks of machine learning model development. It allows data scientists, analysts, and developers to build ML models with high scale, efficiency, and productivity all while sustaining model quality. AutoML in Azure Machine Learning specifically automates the selection of algorithms and tuning of hyperparameters to find the best model for your data based on the metric you specify.
Option A is incorrect because automated deployment is not the primary function of AutoML. However, Azure Machine Learning does provide capabilities for deploying models as web services.
Option B is incorrect because provisioning workspaces is an administrative task and not related to the AutoML process itself.
AutoML in Azure Machine Learning automates the time-consuming and iterative process of model selection and hyperparameter tuning. It allows users to specify the target metric they wish to optimize (e.g., accuracy, AUC, RMSE) and the computational constraints (e.g., time limit, number of iterations). AutoML then automatically trains and evaluates multiple models using different algorithms (such as logistic regression, decision trees, random forests, and neural networks) and hyperparameter configurations.
By exploring a wide range of algorithms and hyperparameters, AutoML helps identify the best-performing model for the given dataset and problem. This saves significant time and effort compared to manually training and tuning models, allowing data scientists to focus on other aspects of the machine learning pipeline.
It’s important to note that while AutoML automates the model training process, it does not automatically deploy new versions of a model as they’re trained (option A) or automatically provision Azure Machine Learning workspaces for new data scientists in an organization (option B). These tasks are separate from the core functionality of AutoML.
In summary, automated machine learning in Azure Machine Learning empowers users to efficiently find the best model for their data by automatically running multiple training jobs with different algorithms and hyperparameters, ultimately saving time and resources in the model development process.
