non-negative matrix

The advantage of the framework structure is its multi-engines. Because of its independent of the engine structure, the system can be flexibly adjusted according to the algorithm. We introduce the framework of the recommendation engine for collaborative filtering algorithm combined with Non-negative matrix factorization.

该框架的优势在于它的多引擎结构，各引擎之间结构独立，可以根据算法灵活调整，本文详细介绍了结合非负矩阵分解的协同过滤推荐算法使用的引擎框架。
