You can recommend an item providing a user-based or item-based mechanism. Some matrix decomposition algorithms are implemented, such as singular value decomposition, and you can evaluate results through standard performance measures, in order to find the best tuning parameters for your specific domain. Algorithms are supported with great documentation and a lot of datasets to experiment. **What do you dislike about python-recsys?** Python-recsys doesn't work with Python 3, so if you have legacy projects in Python 2, you cannot integrate it. Some well-known algorithms are not implemented and it is not possible to add variants to the implemented ones. The library's user community is not very large, so don't expect to have a lot of interactions if you encounter problems using the library. **Recommendations to others considering python-recsys:** Pay attention to the Python version. To use this library, you need to study some technicalities in recommender systems and intelligent systems. **What problems is python-recsys solving and how is that benefiting you?** I've implemented a sophisticated recommender system to recommend e-commerce items in a context-aware environment. It was very simple, with some knowledge of theory paradigms in recommender systems and personalized intelligent systems. ### 4. python-recsys open-source **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Design | Mid-Market (51-1000 emp.)

This reviewer was offered a nominal gift card as thank you for completing this review. **Reviewed Date:** March 28, 2018 **What do you like best about python-recsys?** the python-recsys Library (https://github.com/ocelma/python-recsys) offer us the opportunity to evaluate libraries in the field of machine learning for python, to test the technological bases for building recommendation systems. The solution makes use of the python libraries: python-scipy, python-numpy, csc-pysparse, networkx, divisi2. The solution offers recommendations and predictions to the users of a system, through the transformation of input data, based on reactions and transactions of the users and their relationship with the components of the products with which they interact. It makes use of the SVD (singular-value decomposition) functionality to apply a factorization process of the user's valuation data entry matrix. This solution can be used for the construction of systems that need to predict product recommendations, to its users, when there is a high number of products and users, efficiently taking advantage of the transactions and interactions of users and products. It is a good tool to learn about machine learning systems, making use of statistical algorithms and innovative development techniques, very well constructed, with some of the best programming languages that exist: python. Very good library. highly recommended its use and implementation **What do you dislike about python-recsys?** the libraries are not available for python 3.* **Recommendations to others considering python-recsys:** is a very good library for the construction of complex system of recommendations through factoring processes of input data valuation of a collaborative system **What problems is python-recsys solving and how is that benefiting you?** libraries could help me build a system to make recommendations to users about recipes according to the most popular products among users ### 14.
