中文简介:
协同过滤的一种流行方法是矩阵分解。在本文中,我们考虑“概率矩阵分解”,并通过采用潜变量模型的观点,我们展示了它与贝叶斯PCA的等价性。这激发了我们考虑概率PCA及其非线性扩展,高斯过程潜变量模型(GP LVM)作为概率非线性矩阵分解的方法。我们将方法应用于基准电影推荐者数据集。结果显示优于以前的现有技术性能。
课程简介: A popular approach to collaborative filtering is matrix factorization. In this paper we consider the "probabilistic matrix factorization" and by taking a latent variable model perspective we show its equivalence to Bayesian PCA. This inspires us to consider probabilistic PCA and its non-linear extension, the Gaussian process latent variable model (GP-LVM) as an approach for probabilistic non-linear matrix factorization. We apply approach to benchmark movie recommender data sets. The results show better than previous state-of-the-art performance.
关 键 词: 协同过滤; 矩阵分解; 潜变量模型
