摘要: 传统的评分预测只考虑到了文本信息,没有考虑到用户的信息,因为同一个词 在不同的用户表达中是不一样的.同样good 一词, 有人觉得5分是good 有人觉得4分是good.但是传统的文本向量表达无法区分.所以每个人都应该有一个属于自己的词向量. 传统的是word embedding的方式,这样处理,忽略了文档的生成者的特性. 因此本文讨论的是如何利用用户信息,来“修正”单词的特征表示. 作者提出了一套自己的表达词向量的方式,并不是用的word embedding.. 作者提出了将用户表示为…

0.引言 我们发现传统的(如前向网络等)非循环的NN都是假设样本之间无依赖关系(至少时间和顺序上是无依赖关系),而许多学习任务却都涉及到处理序列数据,如image captioning,speech synthesis,music generation是基于模型输出序列数据:如time series prediction,video analysis,musical information retrieval是基于模型输入需要序列数据:而如translating natural language…
