## Technical details

Recommendations are generated by locating the nearest neighbors of a given repository within a vector space, where similar repositories are positioned close to each other. This vector space was built by training an SVC model on a large dataset containing over 300 million GitHub stars. To keep the model up-to-date, the dataset is refreshed incrementally — one-twelfth is updated each month.

Although recommendations were generated locally at first, some users experienced serious performance issues. Hence, I moved the recommendation engine to a server running [Qdrant](https://qdrant.tech/), a vector database. Qdrant implements lookup techniques more efficient than the brute-force I implemented initially. This allows getting fast results without impacting user’s machines.
