    Form Recognizer

    • Form Recognizer is a service that uses machine learning to extract text, key-value pairs, and tables from documents.
    • It can be used to automate the extraction of information from documents.
    • Form Recognizer is a part of the Azure Cognitive Services suite.

    Prediction

    • Prediction is the process of using a machine learning model to make predictions on new data.
    • It involves using the trained model to make predictions on new, unseen data.
    • Prediction is an essential step in the machine learning workflow.

    Azure Kubernetes Service (AKS)

    • AKS is a managed container orchestration service that allows users to deploy and manage containerized applications.

    Inference Pipeline

    • An inference pipeline is a pipeline that is used to make predictions on new data.
    • It can be deployed as a real-time endpoint or a batch endpoint.
    • Real-time endpoints are used for real-time inferencing, while batch endpoints are used for batch processing.

    Automated Machine Learning

    • Automated machine learning (AutoML) is a process that automates the machine learning workflow.
    • It allows users to automate the selection of algorithms, hyperparameter tuning, and model training.
    • AutoML is a no-code solution that can be used to build and deploy machine learning models.

    Data Labeling

    • Data labeling is the process of annotating data to prepare it for machine learning model training.
    • It involves adding labels or annotations to the data to indicate the target value or class.
    • Data labeling is an essential step in the machine learning workflow.

    Form Recognizer

    • Form Recognizer is a service that uses machine learning to extract text, key-value pairs, and tables from documents.
    • It can be used to automate the extraction of information from documents.
    • Form Recognizer is a part of the Azure Cognitive Services suite.

    Prediction

    • Prediction is the process of using a machine learning model to make predictions on new data.
    • It involves using the trained model to make predictions on new, unseen data.
    • Prediction is an essential step in the machine learning workflow.

    Azure Kubernetes Service (AKS)

    • AKS is a managed container orchestration service that allows users to deploy and manage containerized applications.
    • It is used to deploy real-time endpoints for machine learning models.
    • AKS provides a scalable and secure environment for deploying machine learning models.

    Azure Container Service

    • Azure Container Service is a managed container orchestration service that allows users to deploy and manage containerized applications.
    • It is used to deploy machine learning models as a service.
    • Azure Container Service provides a scalable and secure environment for deploying machine learning models.### Machine Learning Concepts
    • Classification: A type of machine learning used to predict a label or category from a set of features. (Example: predicting brain haemorrhage types from brain scan images)
    • Regression: A type of machine learning used to predict a numeric value from a set of features. (Example: predicting animal population)
    • Clustering: A type of machine learning used to group instances of data into clusters with similar characteristics. (Example: identifying groups of people with similar purchasing habits)

    Azure Machine Learning

    • Automated ML: A type of machine learning that automatically selects and trains models for a given dataset.
    • Designer: A visual interface for building machine learning models without writing code.
    • Workspace: A container for machine learning projects, datasets, and models. (Basic and Enterprise workspaces are available)

    Data Preparation and Ingestion

    • Data Split: Divide a dataset into training and testing sets.
    • Feature Engineering: The process of selecting and transforming raw data into features that are suitable for modeling.
    • Data Ingestion: The process of loading data into a machine learning environment.
