Introduction

Welcome to this video where we will explore the concept of Vector Databases and how they differ from traditional databases. If You've been keeping up with recent developments in AI, you may have heard about Vector DBs and their relevance in machine learning use cases. In this video, we will dive deep into Vector DBs and learn about embeddings. We will also explore the practical applications of Vector DBs using an example from ChromoDB.

What are Vector Databases?

Vector Databases, also known as Vector DBs, are specialized databases used for the storage and retrieval of vector data or embeddings. They play a crucial role in machine learning use cases, especially when dealing with large-Scale language models like GPT. Vector DBs are designed to efficiently store and retrieve vector data, making them essential in modern AI applications.

How are Vector Databases different from traditional databases?

Unlike traditional databases that can store both structured and unstructured data, Vector DBs focus primarily on storing and retrieving vector data. In traditional databases, data is searched Based on predefined criteria, such as filtering based on specific fields. However, in Vector DBs, data is searched and retrieved based on the similarity between vectors or the Context they represent. This unique approach sets Vector DBs apart from their traditional counterparts.

Pros:

• Efficient storage and retrieval of vector data
• Ability to search and find similar concepts based on vector similarity

Cons:

• Limited functionality for non-vector data types
• Requires understanding and working with vector representations of data

Use cases of Vector Databases

Vector DBs find extensive applications in machine learning and AI. They are widely used in image and video processing, natural language processing, large language models, and recommendation systems. In all these use cases, vector data, or embeddings, need to be stored and retrieved efficiently. Vector DBs provide the necessary infrastructure and capabilities to handle these requirements.

What are Embeddings?

Embeddings are numerical representations of data, often used in machine learning and AI. They serve as a means to convert various data types, such as text, audio, video, or images, into a numeric format that computers can understand. By representing data as numbers, it becomes easier to find similarities between concepts and perform computations.

Why do we need to convert data into numerical representation?

Computers inherently understand numerical data better than other data types like text or audio. By converting data into numerical representations, we can leverage the computational power of computers to analyze, process, and interpret the data effectively. Embeddings enable us to transform various data types into numerical form for seamless integration into machine learning models and AI applications.

Types of Embedding Functions

There are several embedding functions available for different data types. For text data, commonly used embedding functions include Word2Vec, GloVe, and BERT. These functions generate Meaningful numerical representations of words and sentences. Additionally, pre-trained embeddings from models like OpenAI's GPT can be readily used, eliminating the need for creating custom embeddings.

Examples of Pre-trained Embeddings

Pre-trained embeddings provide a convenient way to utilize already trained and optimized embeddings. Examples include OpenAI's GPT models, which offer pre-trained text embeddings. These embeddings can be directly incorporated into applications without requiring the creation of custom embeddings. Leveraging pre-trained embeddings saves time and effort while ensuring high-quality representations.

Introduction to ChromoDB

ChromoDB is a popular open-source vector database that specializes in audio data and supports integration with various APIs and frameworks like PyTorch and TensorFlow. It offers easy deployment options on the cloud or on-premise. ChromoDB is optimized for fast retrieval and similarity search within large vector datasets, making it an excellent choice for many machine learning use cases.

How to use ChromoDB for storing and retrieving embeddings

To use ChromoDB, we first need to install it and import the necessary libraries. After creating a client, we can establish a collection for storing our documents. ChromoDB automatically handles indexing, tokenizing, and curation of embeddings, making the process seamless. We can then insert our data, specifying metadata if needed. Retrieving and querying data from ChromoDB is straightforward and allows for efficient similarity searches.

Conclusion Vector databases, such as ChromoDB, provide a powerful tool for storing and retrieving vector data or embeddings. They offer unique capabilities for searching and finding similar concepts based on vector similarity. By converting data into numerical representations using embedding functions, we can effectively utilize the computational power of computers for various machine learning and AI applications. Vector DBs have become an essential component in modern AI workflows, enabling advancements in image and video processing, natural language processing, large language models, and recommendation systems.
