Azure Machine Learning

Azure Machine Learning is a fully managed cloud service used to train, deploy, and manage machine learning models at scale. It fully supports open-source technologies, so you can use tens of thousands of open-source Python packages such as TensorFlow, PyTorch, and scikit-learn. Rich tools are also available, such as Compute instances, Jupyter notebooks, or the Azure Machine Learning for Visual Studio Code extension, a free extension that allows you to manage your resources, model training workflows and deployments in Visual Studio Code. Azure Machine Learning includes features that automate model generation and tuning with ease, efficiency, and accuracy.

Use Python SDK, Jupyter notebooks, R, and the CLI for machine learning at cloud scale. For a low-code or no-code option, use Azure Machine Learning's interactive designer in the studio to easily and quickly build, test, and deploy models using pre-built machine learning algorithms.

Azure AI services

Azure AI services is a set of pre-built APIs that enable you to build apps that use natural methods of communication. The term pre-built suggests that you do not need to bring datasets or data science expertise to train models to use in your applications. That's all done for you and packaged as APIs and SDKs that allow your apps to see, hear, speak, understand, and interpret user needs with just a few lines of code. You can easily add intelligent features to your apps, such as:

Use Azure AI services to develop apps across devices and platforms. The APIs keep improving, and are easy to set up.

Item Description
Type APIs for building intelligent applications
Supported languages Various options depending on the service. Standard ones are C#, Java, JavaScript, and Python.
Machine learning phases Deployment
Key benefits Build intelligent applications using pre-trained models available through REST API and SDK.
Variety of models for natural communication methods with vision, speech, language, and decision.
No machine learning or data science expertise required.

SQL machine learning

SQL machine learning adds statistical analysis, data visualization, and predictive analytics in Python and R for relational data, both on-premises and in the cloud. Current platforms and tools include:

Use SQL machine learning when you need built-in AI and predictive analytics on relational data in SQL.

Item Description
Type On-premises predictive analytics for relational data
Supported languages Python, R, SQL

SynapseML (formerly known as MMLSpark) is an open-source library that simplifies the creation of massively scalable machine learning pipelines. SynapseML provides APIs for a variety of different machine learning tasks such as text analytics, vision, anomaly detection, and many others. SynapseML is built on the Apache Spark distributed computing framework and shares the same API as the SparkML/MLLib library, allowing you to seamlessly embed SynapseML models into existing Apache Spark workflows.

SynapseML adds many deep learning and data science tools to the Spark ecosystem, including seamless integration of Spark Machine Learning pipelines with Light Gradient Boosting Machine (LightGBM), LIME (Model Interpretability), and OpenCV. You can use these tools to create powerful predictive models on any Spark cluster, such as Azure Databricks or Cosmic Spark.

SynapseML also brings networking capabilities to the Spark ecosystem. With the HTTP on Spark project, users can embed any web service into their SparkML models. Additionally, SynapseML provides easy-to-use tools for orchestrating Azure AI services at scale.
