Introduction
Cloud computing applications and platforms quickly expand across all sectors today, acting as the IT foundation that powers new digital firms. These platforms and software have transformed the way firms operate and simplified operations. Today we will explore one such cloud computing platform “Microsoft Azure” and its applications in Machine Learning.
Azure Machine Learning
Azure Machine Learning is a cloud service that accelerates and manages the lifecycle of machine learning projects. Machine learning specialists may use it, data scientists, and engineers in their daily workflows: Model training and deployment, as well as MLOps management
We can build a model in Azure Machine Learning or utilize one created on an open-source platform like Pytorch, TensorFlow, or sci-kit-learn. MLOps products assist you in monitoring, retraining, and redeploying models.
Who can all utilize the Azure Machine learning platform?
Azure Machine Learning is designed for individuals and teams deploying MLOps inside their business and want to put machine learning models into production in a safe and auditable environment.
Enterprises operating in the Microsoft Azure cloud will discover similar infrastructure security and role-based access control (RBAC). We can create a project to restrict access to sensitive data and processes.
Data scientists and machine learning developers will discover solutions to help them speed up and automate their daily activities.
Tools for integrating models into applications or services are available for application developers.
Platform developers will discover a robust set of tools for constructing sophisticated ML tooling underpinned by long-lasting Azure Resource Manager APIs.
Tools for developers
Azure Machine Learning provides developers with familiar interfaces such as:
Python SDK
CLI v2
Azure Resource Manager REST APIs (preview)
Azure Machine Learning Studio
Azure Studio is the web interface for Azure Machine Learning data scientist developers. The studio mixes no-code and code-first experiences for an inclusive data science platform.
The studio is a project workspace's graphical user interface. You may do the following in the studio:
Run stats, outcomes, and reports may be shown.
The view runs, stats, logs, and outputs, among other things.
Create and modify notebooks and files.
Visualize pipelines created using developer interfaces.
Create AutoML jobs.
Manage shared assets like Data credentials, Compute, and Environments.
Security
Azure Machine Learning interfaces with the Azure cloud platform to improve the security of machine learning applications.
Among the security integrations are:
Virtual Networks (VNets) in Azure with network security groups
Azure Key Vault is a storage location for security secrets such as storage account access information.
Azure Container Registry is configured behind a VNet.
ML Project Workflow
Usually, Models are created as part of a project with a purpose and goals. Projects frequently include more than one individual. Iterative development is used while experimenting with data, methods, and models.
Project lifecycle
Although project lifecycles depend on the team or individual, a simple project lifecycle looks like the following:
We may run our training script on the cloud or create a model from scratch in Azure Machine Learning. Models generated and trained in open-source frameworks are frequently brought by developers to be operationalized in the cloud.
Data scientists may utilize models generated in typical Python frameworks in Azure Machine Learning along with other supported languages, such as:
TensorFlow
PyTorch
LightGBM
Scikit-learn
XGBoost
R
.NET
Automated Machine Learning
Classical machine learning data scientists employ past expertise and intuition to choose the proper data feature and algorithm for training in a repeating, time-consuming process. Automated ML (AutoML) accelerates this process and may be accessed via the studio UI or the Python SDK.
HyperParameters
Hyperparameter optimization, also known as hyperparameter tuning, maybe a time-consuming process. With little changes to your job design, Azure Machine Learning can automate this procedure for arbitrary parameterized instructions. In the studio, the results are visualized.
Distributed training with Azure Machine Learning
Multinode distributed training may significantly enhance the efficiency of deep learning and occasionally traditional machine learning training projects. The latest GPU choices are available in Azure Machine Learning to compute clusters.
Azure ML Kubernetes and Azure ML compute clusters support PyTorch, TensorFlow, and MPI.
Deploy Models
To put our model into production, we need to deploy it. The managed endpoints of Azure Machine Learning encapsulate the infrastructure necessary for batch and real-time model scoring.
Batch Scoring
It Involves calling an endpoint with a data reference. The batch endpoint executes tasks asynchronously on compute clusters to process data in parallel and store the results for further analysis.
Real-Time Scoring
It includes calling an endpoint with one or more model deployments and receiving a near-real-time response through HTTPS. Traffic may be split between different deployments, allowing for testing new model versions by diverting some traffic at first and growing as trust in the new model is established.
ML Ops
MLOps, or DevOps for machine learning models, is a method for generating production models. The lifespan of a model, from training to deployment, must be auditable if not replicable.
Azure Machine Learning features many services and materials to help you complete your machine learning projects. These resources and assets are required to complete any project.
Resources
These include the resources required for setup or infrastructure to perform a machine learning workflow, such as:
Workspace
Compute
Datastore
Assets
Created with Azure Machine Learning commands or as part of a training/scoring run, assets may be registered in the Azure ML workspace and are versioned. They include:
Model
Environment
Data
Component
Resources
Workspace
The workspace is the top-level resource for Azure Machine Learning, offering a single location to deal with all of the artifacts produced by Azure Machine Learning. The workspace archives all jobs, including logs, metrics, output, and a snapshot of your scripts. The workspace keeps track of references to resources such as datastores and computing. It also stores all assets such as models, environments, components, and data.
Compute
A computing resource is a dedicated compute resource where you may run your task or host your endpoint. Azure Machine Learning supports the following computing types:
Compute Instance
Compute Cluster
Attached Compute
Inference Cluster
DataStore
Azure Machine Learning datastores securely store the connection information to your Azure data storage, eliminating the need for you to code it in your scripts. You may quickly connect to your storage account and access the data in your underlying storage service by registering and creating a datastore.
Assets
Model
Azure machine learning models are made up of the binary file(s) that constitute a machine learning model and any associated information. Models can be generated from either a local or remote file or directory.
We can use HTTPS, wasbs, and azureml locations for remote services. Models supported are:
custom_model
mlflow_model
triton_model
Environment
Azure Machine Learning environments are a container for the environment in which your machine learning task will run. They define the software packages, environment variables, and program settings used in conjunction with your training and scoring scripts. Within your Machine Learning workspace, environments are controlled and versioned entities. Environments enable machine learning operations that are repeatable, auditable, and portable across a wide range of computes.
They support two types of environments:
Curated
Custom
Data
We can work with the following different types of data in Azure Machine Learning :
URIs (a location in local/cloud storage)
Uri_folder
uri_file
Primitives
String
Boolean
Number
Tables (a tabular data abstraction)
mltable
Component
An Azure Machine Learning component is a standalone piece of code that performs a single step in a machine learning pipeline. Components serve as the foundation for complex machine learning pipelines. Components can perform data processing, model training, model scoring, and other functions. A component is similar to a function because it has a name, arguments, expects input, and outputs results.
Managing assets and resources
We can directly manage our machine learning assets in the browser. For a more seamless experience, the SDK and the studio share assets in the same workspace.
Azure is a cloud computing platform service offered by Microsoft for application management. It provides software as a service, platform as a service, and infrastructure as a service. It supports a wide range of programming languages, tools, and frameworks, as well as Microsoft-specific and third-party products and systems.
What is Tensorflow?
TensorFlow is a free and open-source machine learning and artificial intelligence software library. It may be used for various applications, but it focuses on deep neural network training and inference. The Google Brain team created TensorFlow for internal Google usage in research and production.
What are two types of scoring used while deploying models?
While the deployment of models, two types of scoring are used:
Batch Scoring
Real-Time Scoring
