A collaborative filtering recommendation engine library for Go, implementing item-based and user-based approaches.
regommend is a recommendation engine library for Go that implements collaborative filtering algorithms to generate personalized recommendations. It helps developers build systems that suggest items, content, or products based on user preferences and behavior patterns. The library provides both item-based and user-based recommendation approaches with a simple API.
Go developers building applications that require recommendation features, such as e-commerce platforms, content streaming services, social networks, or any system needing personalized suggestions.
Developers choose regommend for its simplicity, performance, and native Go implementation that doesn't require external dependencies. It offers a straightforward API for implementing recommendation systems without the complexity of larger machine learning frameworks.
Recommendation engine for Go
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
The README example shows intuitive methods like `Recommend()` and `Neighbors()` with clear code, making it easy to integrate into Go applications.
Installation is straightforward via `go get`, and the philosophy emphasizes simplicity without external dependencies, as stated in the description.
Uses in-memory storage for user-item interactions, enabling quick recommendation generation without database overhead, as highlighted in the key features.
Implements distance calculations for measuring similarity, allowing customization for accurate recommendations based on user or item data.
Data is stored only in memory, so all user-item interactions are lost on application restart, requiring manual implementation for data saving and loading.
Focuses solely on basic collaborative filtering with similarity metrics, lacking support for advanced techniques like matrix factorization or deep learning.
In-memory storage restricts dataset size to RAM, making it unsuitable for high-throughput or large-scale production environments without external scaling solutions.
