This is the first time that graph convolutional networks are introduced into the AE source localization task. Data generated by AE sensor networks is represented by a graph structure, in which the temporal features extracted from AE waveforms using one-dimensional convolutional neural networks (1D-...
Spatial Temporal Graph Convolutional Networks for Skeleton-Based Action Recognition(动作识别) Introduction 动作识别的常用方法:appearance,depth,光流,骨架序列 本文主要研究骨骼序列,利用图卷积的方法构建一个有效的模型。 骨架序列模型 所谓骨骼序列就是指一个在时间轴上的骨骼坐标的序列集合。 早期骨架模型的缺点: 1...

[TOC] Spatial-Temporal Graph Convolutional Network for Video-based Person Re-identification(CVPR2020) 行人重识别 行人重识别(Person Re-identification),简称为ReID,是利用计算机视觉技术判断图像或者视频序列中是否存在特定行人的技术。广泛被认为是一个图像检索的子问题。给定一个监控行人图像,检索跨设备下的该...
Spatial Graph Convolutional Neural Network: Spatial Temporal Modeling 上一节讲的是空间卷积操作,这里重新回到了时间层面,对于t时刻的结点 v_{ti}的邻居结点需要加上在时间点q上的 v_{qj} 满足的条件为 d(v_{ti}, v_{tj}) \leq K ,且满足时间关系 |q-t| \leq [\Gamma/2] (取整)。 \Gamma 是...

为了完成在 spatial temporal graph 上的卷积操作,我们也需要 the sampling function,and the weight function. 因为 temporal axis 的次序是显然的,我们直接将 label maplSTlST定义为: 3.4. Partition Strategies. 给定spatial temporal graph convolution 的高层定义,设计一种 partitioning strategy 来执行 the label ma...
Then, the graph convolu-tional networks (GCN) are constructed for spatial structure feature reasoning in a single frame, which is consecutively followed by long short-term memory (LSTM) networks for temporal motion feature learning within the sequence. Moreover, the attention mechanism is further ...
To address these limitations, a knowledge-embedded spatial–temporal graph convolutional networks (KEST-GCN) method is proposed. In KEST-GCN, the relationship triplets are established based on the system structure knowledge and sensor position information. Then, these triplets are transformed into low-...
