论文摘要
数据表示通常是具有其属性值的自然形式。在此基础上,数据处理是一个以属性为中心的计算。但是,以属性为中心的计算有三个限制,说,僵化的计算,偏好计算和不令人满意的输出。为了尝试这些问题,提出了一种新的数据表示形式,称为“超级级表示”,以改善建议。首先,定义了数据特征的横熵,KL差异和JS差异。然后,可以使用这三个参数发现数据中的超级类。最后,一种建议算法用于评估所提出的数据的超级级表示,并表明超级级表示能够为推荐系统提供真正有用的参考信息,并使建议比现有算法更好,即这种方法是有效且有希望的。
Data representation is usually a natural form with their attribute values. On this basis, data processing is an attribute-centered calculation. However, there are three limitations in the attribute-centered calculation, saying, inflexible calculation, preference computation, and unsatisfactory output. To attempt the issues, a new data representation, named as hyper-classes representation, is proposed for improving recommendation. First, the cross entropy, KL divergence and JS divergence of features in data are defined. And then, the hyper-classes in data can be discovered with these three parameters. Finally, a kind of recommendation algorithm is used to evaluate the proposed hyper-class representation of data, and shows that the hyper-class representation is able to provide truly useful reference information for recommendation systems and makes recommendations much better than existing algorithms, i.e., this approach is efficient and promising.
