Recommendation algorithm with vector database

In this article, we’ll explore how to build a simple movie recommendation system using vector databases and Node.js. We’ll utilize pgVector, a PostgreSQL extension that enables scalable vector computations, to create a vectorised movie dataset and perform nearest neighbor searches to generate recommendations.

First, let’s start by discussing the importance of vector databases and their advantages over traditional relational databases.

Why Vector Databases?

Traditional relational databases are great for storing structured data, but they fall short when it comes to …
