What are ML Pipelines?
ML pipelines refer to the series of processes involved in building, training, and deploying machine learning models. These pipelines typically include data ingestion, data preparation, model selection, hyperparameter tuning, model training, and model deployment. The primary goal of an ML pipeline is to automate the workflow, ensuring that the model is accurate, efficient, and scalable. By automating the pipeline, data engineers and scientists can focus on higher-level tasks, such as model selection and hyperparameter tuning, rather than manual data processing and model deployment.Benefits of Using Azure Databricks for ML Pipelines

Creating a Databricks Workspace
Creating a Databricks workspace is a straightforward process that involves signing up for an Azure account, creating a new resource group, and deploying a Databricks workspace. The workspace provides a centralized platform for pipeline development and deployment, enabling data engineers and scientists to collaborate and share resources. The workspace also provides a range of tools and libraries for data preparation, model building, and model deployment.Configuring Clusters for ML Workloads
Configuring clusters for ML workloads involves selecting the appropriate cluster type, such as a CPU or GPU cluster, and configuring the cluster's resources, such as memory and storage. The cluster type and resources depend on the specific requirements of the pipeline, such as the size of the dataset and the complexity of the model. For example, a GPU cluster may be required for deep learning models, while a CPU cluster may be sufficient for traditional machine learning models.Installing Required Libraries and Dependencies
Installing required libraries and dependencies is essential for pipeline development and deployment. The required libraries and dependencies include MLflow, TensorFlow, and PyTorch, which provide a range of tools and functions for data preparation, model building, and model deployment.
