个性化推荐算法设计

协同过滤技术（collaborative filtering）目前被成功地应用于个性化推荐系统中，但随着系统规模的扩大，它的效能逐渐降低，提出了一种高效的个性化推荐算法，它包括维数简化和项集相似性计算两个过程，这种算法在提高精确性的基础上减少了计算耗费，可以较好地解决应用协同过滤技术的推荐系统所存在的稀疏性，扩展性等问题，快速产生精确的个性化推荐结果。

ALGORITHM DESIGN FOR PERSONALIZATION RECOMMENDATION SYSTEMS

Collaborative filtering is the most successful technology for building recommendation systems. Unfortunately,the efficiency of these methods decline linearly with the number of users and items .To address these limitations, a high efficient personalization recommendation algorithm is presented, which includes two phases: dimensionality reduction and item-based recommendation methods. This algorithm reduces the computation consumption based on enhancing the accuracy, etc. It may solve questions well such as sparsity, scalability. It can create accurate personalization recommendation quickly.
