Everything About Vector Databases – Their Significance, Vector Embeddings, and Top Vector Databases for Large Language Models (LLMs)

Large Language Models have shown immense growth and advancements in recent times. The field of Artificial Intelligence is booming with every new release of these models. From education and finance to healthcare and media, LLMs are contributing to almost every domain. Famous LLMs like GPT, BERT, PaLM, and LLaMa are revolutionizing the AI industry by imitating humans. The well-known chatbot called ChatGPT, based on GPT architecture and developed by OpenAI, imitates humans by generating accurate and creative content, answering questions, summarizing massive textual paragraphs, and language translation. 

What are Vector Databases?

A new and unique type of database that is gaining immense popularity in the fields of AI and Machine Learning is the vector database. Different from conventional relational databases, which were initially intended to store tabular data in rows and columns, and more recent NoSQL databases like MongoDB, which store data in JSON documents, vector databases are different in nature. This is because vector embeddings are the only sort of data that a vector database is intended to store and retrieve.

Large Language Models and all the new applications depend on vector embedding and vector databases. These databases are specialized databases made for the effective storage and manipulation of vector data. Vector data, which uses points, lines, and polygons to describe objects in space, is frequently used in a variety of industries, including computer graphics, Machine Learning, and Geographic Information Systems. 

A vector database is based on vector embedding, which is a sort of data encoding carrying semantic information that aids AI systems in interpreting the data and in maintaining long-term memory. These embeddings are the condensed versions of the training data that are produced as part of the ML process. They serve as a filter used to run new data during the inference phase of machine learning. 

In vector databases, the geometric qualities of the data are used to organize and store it. Each item is identified by its coordinates in space and other properties that give its characteristics. A vector database, for instance, could be used to record details on towns, highways, rivers, and other geographic features in a GIS application.

Advantages of vector databases

1. Spatial Indexing – Vector databases use spatial indexing techniques like R-trees and Quad-trees to enable data retrieval based on geographical relationships, such as proximity and confinement, which makes vector databases better than other databases.

2. Multi-dimensional Indexing: Vector databases can support indexing on additional vector data qualities in addition to spatial indexing, allowing for effective searching and filtering based on non-spatial attributes.

3. Geometric Operations: For geometric operations like intersection, buffering, and distance computations, vector databases frequently have built-in support, which is important for tasks like spatial analysis, routing, and map visualization.

4. Integration with Geographic Information Systems (GIS): To efficiently handle and analyze spatial data, vector databases are frequently used in conjunction with GIS software and tools.

Best Vector Databases for Building LLMs

In the case of Large Language Models, a vector database is getting popular, with its main application being the storage of vector embeddings that result from the training of the LLM.
