Create And Consume Cognitive Services Flashcards
AZ cognitive services enables developers to easily add AI capabilities to their applications
AZ cognitive services are cloud-based services that encapsulate AI capabilities will stop rather than a single product you should think of AZ cognitive services as a set of individual services that you can use as building blocks to compose sophisticated and intelligent applications.
Cognitive services includes a wide range of individual AI services across multiple categories.
The categories could include language speech version decision language
Translators
Speech
Computer vision
Face
Decision
Anomaly detector
content moderator
Personaliser
You can use cognitive services to build your own air Solutions and they also underpin AZ applied AI services that provide out-of-the-box solutions for Common AI scenario full-stop applied AI services include:
Easy form recognizer-and optical character recognition or o r c solution that can extract semantic meaning from forms such as invoices receipts and others.
At metrics advisor-a service built on the anomaly detector cognitive service that simplifies real-time monitoring and response to Critical metrics.
Easy video Analyser for media-and comprehensive video and analysts solution build on the video indexer cognitive service. Az immersive reader-a breeding solution that supports people of all ages and abilities.
As he bought service-a Cloud service for delivering conversational AI solutions or bots.
Az cognitive search- cloud-scale search solution that uses cognitive services to extract insights from data and documents.
While the details of each cognitive search may vary the approach to provisioning and consuming them is generally the same.
Provision a cognitive services resource:
Az cognitive service includes a wide range of AI capabilities that you can use in your applications.
To use any of the cognitive services you need to create appropriate resources in the AZ subscription to define an influence where the service can be consumed provide access keys for authenticated access and to manage building for your applications use of the service.
Options for AZ resources turn on uline for many of the available cognitive services you can choose between the following provisioning options: Multi-service resource
Single service resource
Training and prediction resources
Single service resource
Single service resource kola
Is cognitive service can be provisioned individually for example by creating discrete language and computer vision resources in your AZ subscription. This approach enables you to use separate and points for each service for example to provision them in different geographical regions and to manage access credentials for each service independently. It also enables you to manage billing separately for each service. Single-service resources generally offer a free chair with usage restrictions making them a good choice to try out a service before using it in a production application.
Training and prediction resources:
Wellness cognitive services can be used through a single AZ resource an offer or require separate resources for model training and prediction.
This enables you to manage billing for training custom model separately from model consumption buy applications and in most cases enables you to use a dedicated service specified resource specific resource to train a model but a generic cognitive services resource to make the model available to applications for inferencing
Identify endpoints and keys:
When you provision a cognitive service resource in your AG subscription you are defining an Endpoint through which the service can be consumed by an application.
To consume the service through the Endpoint applications require the following information: the Endpoint url
The subscription key
The resource location
The Endpoint url on new line this is the HTTP address at which the rest interface for the service can be accessed will stop most part native services software development kits sdks use the Endpoint URL to initiate a connection to the Endpoint.
A subscription people on new line access to the Endpoint is restricted based on a subscription fee for stop client applications must provide a valid way to consume the service will stop when you provision a cognitive service resource two keys are created-applications can you see the key. You can also regenerate the keys as required to control access to your resource.
The Resource location:
When you provision a resource in AZ if you generally assign it to a location which determines the AZ data centre in which the resource is defined. While most sdks use the Endpoint URL to connect to the service some require the location
Use a rest api:
Cognitive services provides rest application programming interfaces or API that client applications can use to consumer services. In most cases service functions can be called by submitting data in json format over an HTTP request which may be a post put or get request depending on the specific function being called.
3 seltzer of the function are returned to the client as an HTTP response often with Jason contents that encapsulate the output data from the function
The use of rest interfaces with an HTTP Endpoint means that any programming language or tool capable of submitting and receiving Jason over HTTP can be used to consume pregnant of services.
You can use common programming languages such as Microsoft C Sharp python and JavaScript as well as utilities such as personal and see URL which can be useful for testing or curl
Use an sdk:
You can develop an application that uses cognitive services using rest interfaces but it is easier to build more complex Solutions by using native libraries for the programming language in which you are developing the application
Software development kits:
Software development kits sdks for common programming languages abstract the rest interfaces for the most cognitive services for most cognitive services.
Sdk availability varies by individual cognitive services but for most services there is an SDK for languages such as:
Microsoft C Sharp (dotnet core)
Python
Javascript (node js)
Go
Driver
Its SDK includes packages that you can install in order to use specific service Pacific libraries in your code and online documentation to help you determine the appropriate classes methods and parameters used to work with the service
