知识图谱(Knowledge Graph)主要是用于描述现实世界中的实体(区别于概念,是指客观世界中的具体实物,如张三,李四等)、概念(人们在认识世界过程中形成的对客观事物的概念化表示,如人、动物等)及事件间的客观关系。知识图谱的构建过程即从非结构化数据(图像等)或半结构化数据(网页等)中抽取信息,构建结构化数据(三元组,...
GSNN (Graph Search Neural Network) GSNN主要解决图过大,计算太慢的问题,主要考虑循序渐进的去增加二跳或者三跳节点 主要流程: 先通过分类任务或者检测任务,得到初始节点,并把初始节点的一跳节点纳入初始输入中,得到Graph A 学习一个节点打分函数,来决定哪些节点需要拓展 根据节点打分函数,拓展A中的P个节点,并把他...
模型:Knowledge-aware Coupled Graph Neural Network (KCGN),在推荐框架中加入用户和项目相互依赖知识。利用全局图结构感知的相互信息,编码高阶用户和项目联系。 introduction 将社交联系加入协同过滤体系结构作为辅助信息,描述用户的连接性信息。 现存方法忽视了项目级别的信息,item-wise relational structure 有助于理解用...
Graph neural networkKnowledge graphSocial recommendationWith a view to increase recommendation systems accuracy and practical applicability, using traditional methods which are namely interaction model between users and items, collaborative filtering and matrix factorization cannot achieve the supposed results. ...
For classification tasks, we utilize the binary cross-entropy (BCE) loss combined with the sigmoid layer (BCEWithLogits loss) when training the graph encoder and the property prediction network, while for regression tasks, we apply the mean squared error loss. The Adam optimizer is applied to ...

This way we transform the knowledge graph into a user-specific weighted graph and then apply a graph neural network to compute personalized item embeddings. To provide better inductive bias, we rely on label smoothness assumption, which posits that adjacent items in the knowledge graph are likely ...
