“84% of business owners agree that their businesses must implement AI to maintain a competitive advantage in their industry.”– Forrester, Jan 2022

AI has taken over our lives and has become an essential part of digital experiences. One of the most compelling applications of AI is in making our everyday lives better and easier. It has become imperative that developers create more immersive experiences with AI and ML for users to retain a competitive edge and the cloud paves the way for it. Microsoft Azure offers AI tools and platforms that are designed to work for all skill levels, from low-code development of predictive systems for business analysis to complex computer vision applications in cars and drones to enable developers to build intelligent applications. Let’s explore how to build intelligent applications with the various AI and ML services offered by Azure.

Building Intelligent Applications with Azure Cognitive Services

Azure Cognitive Services is a collection of APIs for pre-trained ML models that enables you to build intelligent applications with ease. Azure Cognitive Services offers advanced capabilities such as natural language processing, computer vision, speech recognition, and more to create highly intelligent and interactive solutions. Azure Cognitive Services provides developers with a powerful toolkit to build intelligent applications that can understand, analyze, and interact with users and their data.

Azure Cognitive Services lets you tap into pre-trained models and APIs, eliminating the need for complex machine learning expertise and enabling rapid development. These services are designed to be scalable, secure, and reliable, providing developers with the flexibility to meet the evolving needs of their applications.

Azure cognitive services can be divided into 6 categories:

1.      Language

Azure provides language understanding APIs, such as Language Understanding (LUIS) and QnA Maker, text analyzer, and translator which enable your applications to extract and understand important information from user inputs. These services use machine learning algorithms to interpret natural language queries, anticipate user intents, and provide accurate responses.

2.      Speech

Azure’s Speech Services offer powerful speech processing capabilities that allow your applications to transcribe speech to text, convert text to speech with customizable voice options, and even translate languages in real-time which allows you to create global user experiences. These services are valuable for building voice-enabled applications, virtual assistants, and voice-controlled interfaces.

3.      Vision

Azure’s Vision Services enable your applications to analyze and understand visual content, including images, videos, and digital ink. With computer vision capabilities such as image classification, object detection, and facial recognition, you can extract valuable information from visual data. Additionally, services like Video Indexer and Form Recognizer further enhance your application’s ability to process videos and extract relevant information from forms.

4.      Decision

Azure offers decision services that assist in making informed and efficient decisions within your applications. Services like Anomaly Detector help identify irregular patterns or outliers in data, while Content Moderator enables you to manage and moderate user-generated content effectively. Personalizer helps personalize user experiences by leveraging reinforcement learning algorithms to continuously adapt to user preferences.

5.      Search

Azure Cognitive Search provides powerful search capabilities for building applications. Whether it’s web search, news search, local business search, or specialized searches like image and video search, Azure offers a range of search services like Bing News Search, Bing Video Search, Bing Image Search, Bing Web Search, Bing Autosuggest or Bing Spell Check that can be integrated to deliver rich and relevant search experiences.

6.      Open AI

Azure OpenAI services allow developers to leverage the power of GPT-3 for a wide range of language and code tasks such as extraction, classification, and translation by using prompts. By providing free text examples as prompts, the OpenAI API analyzes and matches patterns to deliver accurate responses. With four base GPT-3 models (Ada, Babbage, Curie, and Davinci) and the Codex series, developers can generate natural language or code, bridging the gap between human language and programming. Whether it’s code suggestions for refinement or explaining code in natural language, Azure OpenAI services make complex tasks more accessible and efficient for developers.

Azure Cognitive Services allows developers to train custom models using their own data, tailoring the AI capabilities to specific business needs. This level of customization provides an edge in creating applications that deliver personalized experiences and meet unique requirements.

Azure Applied AI Services combine multiple Cognitive Services with models and business logic that are ready to use for specific tasks.

Azure Cognitive Services seamlessly integrates with other Azure services, such as Azure Bot Service, Azure Functions, and Azure Machine Learning, enabling developers to create end-to-end intelligent solutions that leverage the power of the entire Azure ecosystem. Cognitive service models can be integrated with applications by using REST API calls from inside the code in any programming language or can be run on your own servers and in devices at the edge of the network with SDK packages.

Developing Custom Machine Learning Models with Azure Machine Learning

Azure Machine Learning services provide developers with the flexibility to build, train, test, and deploy their own machine learning models. The hosted Notebook service, powered by Azure Machine Learning’s Python SDK, allows developers to easily build and test models using popular machine learning frameworks.
