摘要:

图卷积网络(GCN)旨在将深度学习扩展到任意不规则域,即图。它们的成功高度依赖于输入图的拓扑结构是如何定义的,并且大多数现有的GCN架构依赖于预定义的或手工制作的图结构。在本文中,我们介绍了一种新的方法,学习输入图的拓扑结构(或连通性)作为GCN设计的一部分。我们的方法的主要贡献在于建立一个正交连接基础,最佳地聚合节点,通过他们的邻居,实现卷积之前。我们的方法还考虑了一个随机性标准,它作为一个正则化器,使学习的基础和底层的GCN轻量级,同时仍然是非常有效的。实验上进行的具有挑战性的任务,基于手势识别的GCN的学习w.r.t.的高效率。相关的工作。

英文摘要:

Graph convolutional networks (GCNs) aim at extending deep learning to arbitrary irregular domains, namely graphs. Their success is highly dependent on how the topology of input graphs is defined and most of the existing GCN architectures rely on predefined or handcrafted graph structures. In this paper, we introduce a novel method that learns the topology (or connectivity) of input graphs as a part of GCN design. The main contribution of our method resides in building an orthogonal connectivity basis that optimally aggregates nodes, through their neighborhood, prior to achieve convolution. Our method also considers a stochasticity criterion which acts as a regularizer that makes the learned basis and the underlying GCNs lightweight while still being highly effective. Experiments conducted on the challenging task of skeleton-based hand-gesture recognition show the high effectiveness of the learned GCNs w.r.t. the related work.
