A fresh viewpoint: Ai Ml Model

To get started with Azure AI ML Studio, you need to meet a few prerequisites.

You'll need to create a workspace if you don't already have one. This is a straightforward process that's outlined in the "Create resources you need to get started" article.

Sign in to the Azure Machine Learning studio and select your workspace if it's not already open.

To work with notebooks, you'll need to open or create one in your workspace. This will give you a blank slate to start experimenting with Azure AI ML Studio.

Here are the specific steps to create a workspace and open a notebook:

To set up Azure AI ML Studio, start by setting your kernel and opening it in Visual Studio Code (VS Code). Create a compute instance if you don't already have one, and make sure the kernel is Python 3.10 - SDK v2. If not, select the Refresh button on the top right of the notebook.

To authenticate, select the banner that says you need to be authenticated. Once authenticated, you can run the notebook here or open it in VS Code for a full integrated development environment (IDE) with the power of Azure Machine Learning resources.

To create a workspace handle, you'll need to create an ml_client. This client is a handle to the workspace, and you'll use it to manage resources and jobs.

You can find the necessary values by selecting your workspace name in the Azure Machine Learning studio toolbar, and then copying the workspace, resource group, and subscription ID values into the code.

Creating an MLClient doesn't connect to the workspace immediately. The client initialization is lazy, and it waits for the first time it needs to make a call.

To get started, you'll need to enter your subscription ID, resource group name, and workspace name into the code. Here are the steps to find these values:

To create an environment in Azure Machine Learning, you need to list the software runtime and libraries you want installed on the compute where the training will take place. This is similar to setting up a Python environment on your local machine.

Azure Machine Learning provides many curated or ready-made environments that are useful for common training and inference scenarios. These environments can be used as a starting point for your own custom environments.

You can create a custom conda environment for your jobs, using a conda yaml file. This allows you to specify the exact software and libraries you need for your training.

To create a custom environment, you'll need to define the software and libraries you want to include. This can be done using a conda yaml file, which provides a simple and efficient way to specify the dependencies for your environment.

Here are the key components you'll need to create a custom environment:

By creating a custom environment, you can ensure that your training jobs have all the necessary software and libraries to run smoothly and efficiently.

To configure a training job in Azure Machine Learning, you'll need to create a custom training script. This script will handle data preparation, training, and registering the trained model. You can use MLFlow to log parameters and metrics during the job, allowing you to track results and get the best model for your data.

A different take: Ai and Ml in Data Analytics

You can create a training script in a Python file, such as main.py. This script will preprocess the data, splitting it into test and train data, and then consume the data to train a tree-based model and return the output model. MLFlow is used to log the parameters and metrics during this job.

To develop a predictive analysis model, you typically use data from one or more sources, transform and analyze that data through various data manipulation and statistical functions, and generate a set of results. You can use Azure Machine Learning Studio to build, test, and iterate on a predictive analysis model by dragging and dropping datasets and analysis modules onto an interactive canvas.

A command job is a function that allows you to submit a custom training script to train your model. This job can also be defined as a custom training job. To train a model, you need to submit a job, and Azure Machine Learning offers several different types of jobs to train models.

To create a custom training job, you'll need to provide the following items:

You can use the Azure Machine Learning Python SDK v2 to create and run the command job. Command jobs can be run from CLI, Python SDK, or studio interface.

You can use popular frameworks for training machine learning models such as scikit-learn, PyTorch, TensorFlow, and many more. The extension makes it easy to submit and track the lifecycle of those models.

By following these steps, you can configure a training job in Azure Machine Learning and start training your machine learning models.

Setting up Git integration is a breeze with Azure Machine Learning. You can use the VS Code extension to connect to a remote compute instance.

The Azure Machine Learning VS Code extension enables you to use VS Code's built-in Git support. This allows you to manage your code repositories directly from the extension.

By connecting to a remote compute instance, you'll be able to access your project files and collaborate with others in real-time. This is especially useful when working on large projects with multiple team members.

The VS Code extension also provides a seamless experience for managing your Git repositories, including committing, pushing, and pulling code changes.

To train a model in Azure AI ML Studio, you need to submit a job. Azure Machine Learning offers several different types of jobs to train models, including command jobs.

A command job is a function that allows you to submit a custom training script to train your model. This job can also be defined as a custom training job.

To create a command job, you'll need four key items: environment, data, command job, and training script.

The training script handles the data preparation, training, and registering of the trained model. You can use the Azure Machine Learning Python SDK v2 to create and run the command job.

You can create a training script by starting with a main.py python file. This script preprocesses the data, splitting it into test and train data, and then consumes the data to train a tree-based model and return the output model.

Popular frameworks for training machine learning models in Azure AI ML Studio include scikit-learn, PyTorch, and TensorFlow.
