A C library for product recommendations using collaborative filtering with fast performance and minimal dependencies.
Recommender is a C library that implements collaborative filtering algorithms for generating personalized product recommendations. It analyzes user feedback and preferences to predict suitable items for individual users, solving the problem of embedding recommendation capabilities into performance-sensitive applications.
C developers and engineers building applications that require embedded recommendation functionality, particularly those working on systems where performance, minimal dependencies, and low memory footprint are critical.
Developers choose Recommender because it provides a high-performance, dependency-free collaborative filtering implementation specifically optimized for C environments, with demonstrated efficiency handling large datasets while maintaining minimal resource usage.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Processes 10 million ratings in approximately 81 seconds, as benchmarked on MovieLens data, making it efficient for large-scale datasets.
Maintains memory footprint under 160 MB for 10 million ratings, optimizing resource usage in constrained environments.
A self-contained C library with no external dependencies, simplifying integration and reducing deployment overhead.
Supports both implicit and explicit user feedback for training, allowing adaptability to different data types.
Only implements basic user-based and item-based collaborative filtering, lacking advanced techniques like matrix factorization or neural networks mentioned in references.
Requires manual compilation with make and linking, as shown in the README, which can be cumbersome compared to higher-level language libraries.
The README provides minimal API details and usage examples, offering only basic building instructions and a simple test, which may hinder adoption.
