Despite the progress that has been made, rich and informative spectral information of HSI has been largely underutilized by existing methods which employ convolutional kernels with limited size of receptive field in the spectral domain. To address this issue, we propose a spectral graph reasoning ...
关于图卷积神经网络(Graph Convolutional Neural Network,GCN)的介绍和讲解,网络上已经有很多优秀的材料了,我在文末也会做个简单的整理,但大部分的材料为了介绍清楚图卷积神经网络的原理进行了大量的数学推导,需要用到许多数学、信号与系统等相关领域的知识,这就使得学习的难度大了很多,而且很多材料只是单纯的介...

In recent years, graph convolutional network has been widely used in hyperspectral image classification because of its feature aggregation mechanism, which can simultaneously represent the features of a single node and neighboring nodes. However, there a
So, this is essentially the key how you can tackle the graph convolutional neural networks. So, what do we actually want to do? Well, you can take one of these algorithms and apply it to some mesh. Of course, this can also be done on very complex meshes and I will put a couple ...
Recent researches have shown that spectral representation provides a significant speed-up in the massive computation workload of convolution operations in the inference (feed-forward) algorithm of Convolutional Neural Networks (CNNs). This approach results in reducing the computational complexity of the ...
