因此,多个邻接矩阵表示一个图的多个视角肯定更加可靠,因为他们提供了更加可靠的节点关系。 首先,给定多个邻接矩阵表示图结构的不同视角,multi-GCN对每个视图使用一个普通的GCN得到节点在不同视图下的表示。然后使用多图注意力模块自适应的融合多个结点级的表示。节点在不同视图中的注意力权重通过将各个视图的池化向量作为...
论文中主要提出了一种新的模型MVAN(Multi-view Attention Networks),通过利用多种数据源检测真实的金钱交易。 这个模型主要包括以下几个部分: multi-graph attention:基于图结构 behaviour attention network:基于顶点内容(vertex content),也即是角色的行为序列 portrait attention network:基于角色属性(vertex attribute),...
Specifically, to balance the capabilities of capturing global dependencies and modeling the locality, we propose a multi-view self-attention mechanism for speaker Transformer, in which different attention heads can attend to different ranges of the receptive field. Furthermore, we i...
论文:MVAN: Multi-view attention networks for real money trading detection in online games里分析了在网游中存在的真实金钱交易行为。(Real money trading)这种交易行为,用真实世界的货币交换虚拟世界中的资产,导致游戏经济的不平衡和贫富不均。 论文中主要提出了一种新的模型MVAN(Multi-view Attention Networks),...
In this article, we propose a framework that combines multiview learning and attention mechanism (MLAM) to solve the above mentioned problems. First, we develop a CNN-based weakly supervised method with a weight-balanced loss function to solve the problems caused by an unbalanced data set. It...
