| 摘 要： | 为了提高传统协同过滤推荐算法推荐的准确度,对评分信任和社交信任赋予自适应的权重,结合概率矩阵分解算法,提出一种综合的个性化推荐算法.该算法在Filmtrust数据集上进行验证,并与相关算法进行对比,结果表明所提算法在MAE(mean absolute error)和RMSE(root mean squared error)指标上均得到有效的改进.

| Abstract: | By giving the adaptive weight to the users trust in project score data and social trust, a comprehensive personalized recommendation algorithm combining multi-view trust and probability matrix decomposition was proposed to improve the recommendation accuracy. The algorithm was verified on the Filmtrust dataset. The results showed that the proposed algorithm was effectively improved on both MAE(mean absolute error)and RMSE(root mean squared error)indicators compared with related algorithms. |
