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…

作者简介: 吴天龙  香侬科技researcher 公众号(suanfarensheng) 导言 图(graph)是一个非常常用的数据结构,现实世界中很多很多任务可以描述为图问题,比如社交网络,蛋白体结构,交通路网数据,以及很火的知识图谱等,甚至规则网格结构数据(如图像,视频等)也是图数据的一种特殊形式,因此图是一个很值得研究的领域. 针对graph的研究可以分为三类: 1.经典的graph算法,如生成树算法,最短路径算法,复杂一点的二分图匹配,费用流问题等等: 2.概率图模型,将条件概率表达为…

为什么使用序列模型(sequence model)?标准的全连接神经网络(fully connected neural network)处理序列会有两个问题:1)全连接神经网络输入层和输出层长度固定,而不同序列的输入.输出可能有不同的长度,选择最大长度并对短序列进行填充(pad)不是一种很好的方式:2)全连接神经网络同一层的节点之间是无连接的,当需要用到序列之前时刻的信息时,全连接神经网络无法办到,一个序列的不同位置之间无法共享特征.而循环神经网络(Recurrent Neural Networ…
