Q & A
What is the main focus of the session presented by Jasine Greenway?
-The session focuses on part two of the Azure Cosmos DB developer guide, where Jasine Greenway walks through building AI applications with Azure Cosmos DB, specifically discussing embeddings and retrieval augmented generation.
What is the significance of embeddings in the context of AI applications?
-Embeddings are a machine learning concept that allows categorical variables or text to be converted into a form that can be input into a model. They are used to create a searchable product base that can be accessed through chat, making it easier to find related items or topics.
How does Azure Cosmos DB store and manage embeddings?
-Azure Cosmos DB stores the vector representations, or embeddings, of data in what is essentially a vector database or vector store with an index, allowing for efficient storage and retrieval of these embeddings.
What is the role of the Azure Open AI service in the application being built?
-The Azure Open AI service is used to interact with the application's backend. It is leveraged for creating embeddings and applying retrieval augmented generation to enhance the user experience and provide meaningful responses.
Why is the chat interface important in the context of AI applications?
-The chat interface is important because it allows users to interact with the application's knowledge base using natural language. This means users can ask questions in a conversational manner instead of writing complex queries, making the interaction more intuitive and user-friendly.
What are some modern requirements for AI applications?
-Modern AI applications require speed, the ability to work with different types of data under one application, natural language interaction, scalability to handle the demand of users, security and compliance, and cost-effectiveness in terms of resources and monetary costs.
How does the use of Azure App Service benefit the deployment of the front end of the application?
-Azure App Service is a service for hosting web applications. It benefits the deployment of the front end by providing a platform that is reliable and scalable, allowing for easy management and hosting of the single page application (SPA).
What is the purpose of the hackathon mentioned in the session?
-The hackathon is an opportunity for participants to showcase their AI skills and use Azure Open AI through the provided proxy. It encourages learning and building AI applications, with the chance to compete for prizes and recognition on a global scale.
How can participants access Azure Open AI during the hackathon?
-Participants can access Azure Open AI through the hackathon proxy by logging in through GitHub. Upon doing so, they receive an Azure Open AI key and an endpoint that can be used in their applications.
What is the benefit of using a containerized approach for deploying backend applications?
-Containerizing a backend application ensures consistency across different environments. It allows the application to run with the same behavior regardless of whether it's deployed locally or in the cloud, simplifying the development and deployment process.
What is Lang Chain and how does it help in managing different AI packages and libraries?
-Lang Chain is an LLM (Large Language Model) orchestrator that simplifies the management of different AI packages and libraries. It allows for the chaining of different AI app processes, making it easier to sequence and manage the execution of various AI tasks within an application.
Outlines
😀 Introduction and Event Overview
Danny, the event planner for the New York Reactor Space, welcomes everyone and introduces Jasine Greenway, the speaker for the session on Azure Cosmos DB developer guide. The session includes a review of the code of conduct, an overview of the session's structure, and a mention of the ongoing hackathon. Jasine discusses the modern requirements for AI applications, such as speed, data handling, cloud solutions, natural language interaction, accuracy, scalability, security, and cost-effectiveness.
📚 Backend Development and Embeddings
The presentation moves on to discuss the backend development of the web application, which was deployed to Azure App Service. The focus is on using Azure OpenAI service for creating embeddings, which are a way to convert text into a format that can be processed by machine learning models. The concept of vectors and embedding is introduced as a means to build a searchable product base through chat, emphasizing the importance of vector representation for data like images, audio, and text.
🔍 Exploring Embeddings and Vector Databases
Jasine provides a deeper look into the existing notebook labs, focusing on how to use embeddings to create a product base for a searchable database. The process involves setting up an endpoint, creating clients, and connecting to Azure OpenAI. The use of different models for chat completions and embeddings is explained, with a focus on the Text Embedding Ada model for creating vectors. The concept of vectorizing and storing embeddings in documents is also covered.
🛠️ Vector Index Creation and Searching
The session continues with creating a vector index, which is essential for performing vector searches in Azure Cosmos DB. Different types of indexes are discussed, with IVF being the default choice. A demonstration of searching for products using vector representations is shown, highlighting how similar items can be found based on vector similarity. The concept of retrieval augmented generation is introduced, which combines vector databases with completion models to create tailored responses.
🔗 Lang Chain API and Backend Integration
Jasine opens up lab five to work with the backend API, showcasing the use of Lang Chain, an LLM (Large Language Model) orchestrator, to manage different AI packages and libraries. The process of setting up the backend API locally, creating clients, and connecting to Azure OpenAI is detailed. The use of Lang Chain to format documents into JSON and the importance of setting up the Python environment for development are also discussed.
🏗️ Deploying the Backend API and Containerization
The paragraph outlines the steps for deploying the backend API in a container using Docker. It emphasizes the benefits of containerization, such as consistency and ease of deployment across different environments. The process includes installing requirements, using a Dockerfile to manage containers, and deploying the application to Azure Container Apps. The use of Azure Cloud Shell for executing commands is also mentioned.
🤖 Interaction with Completion Models and Vector Embeddings
Jasine clarifies the difference between vector embeddings and interacting with completion models. Completion models are used for text generation, such as creating resumes, while vector embeddings are for creating similarity between data points, which is useful for searches and is typically stored in a vector database. The application of these concepts in a chat application is discussed, where user input is turned into a vector for database comparison.
📝 Final Q&A and Closing Remarks
The session concludes with a Q&A segment where Jasine addresses questions about the use of Docker Desktop for local container testing and the difference between vector embeddings and completion models. She also provides information on how to join the hackathon and Discord for further interaction and support. The importance of community engagement and the opportunity to learn and compete in the hackathon are highlighted before signing off.
