In today’s digital age, recommendation systems have become strategic drivers of engagement and revenue. Overwhelmed by endless choices, users rely on personalized suggestions to find relevant articles, videos, or products. Netflix, for example, attributes 80% of streamed content to personalized recommendations, while e-commerce and music streaming platforms cite recommender engines as crucial to user satisfaction. By analyzing behavior and delivering tailored content, these AI systems increase engagement and gather more data, fueling a virtuous feedback loop. Businesses see boosts in click-through rates, sales, and long-term loyalty as users feel “known.” Today, recommendation systems are mission-critical AI tools that provide a competitive advantage across industries.

Most large-scale designs use a two-stage pipeline: candidate retrieval followed by ranking. This approach mirrors search engines and handles catalogs of millions of items efficiently.
