Spatial-based convolution将卷积神经网络的思想借鉴到图神经网络中(卷积神经网络的卷积核是将卷积核滑动所对应范围内的像素进行聚合),即基于节点的邻居对图进行聚合。 Spectral-based convolution是基于信号领域的方法来进行。 上述两类方法的划分为: GAT和GCN是最常用的模型 二、Spatial-based convolution 回顾一下卷积...
4.1.1 Convolution-based methods The main idea of convolution-based models are based on using several stacked convolution layers. So, the input flows sequentially from starting to later layers. These convolution-based models can make up-sampling operations: early upsampling or late upsampling. The ne...
Two new arithmetic formulas Of semiderivation forconvolutionvoltammetry were presented based on the semiderivative property. 从半微分算符的基本性质出发,用黎曼-斯提杰斯积分展开式得到两个关于半微分运算的新表达式. 期刊摘选 This correlation implies a direct connection between internal structure and surface prop...

Methods, apparatus, systems, and articles of manufacture are disclosed to improve convolution efficiency of a convolution neural network (CNN) accelerator. An example hardware accelerator includes a hardware data path element (DPE) in a DPE array, the hardware DPE including an accumulator, and a ...
Crowd counting is considered a challenging issue in computer vision. One of the most critical challenges in crowd counting is considering the impact of scale variations. Compared with other methods, better performance is achieved with CNN-based methods.
Projection-based Methods Point-based Methods Transformer-based Methods B. 2D Image Classification III. 3D CONVOLUTION-TRANSFORMER NETWORK 在本节中,我们将展示如何在三维点云分类的分层框架中结合Transformer和卷积。我们首先介绍分层网络架构的设计,然后介绍基于卷积的局部特征聚合和Transformer-based的全局特征学习过程...
Convolutional neural networks (CNNs) have been the de facto standard in a diverse set of computer vision tasks for many years. Especially, deep neural networks based on seminal architectures such as U-shaped model with skip-connections or atrous convolut
Two methods will be described: overlap-add and overlap-save. 4.7.2.1 Overlap-add method Assume that the length of the impulse response sequence is of length M. The data sequence is divided into non-overlapping subsequences of length L. The size of the DFTs and IDFT is therefore N=L+M...
In this paper, we show that depthwise separable convolution can be successfully generalized for the unification of both graph-based and grid-based convolution methods. Based on this insight we propose a novel Depthwise Separable Graph Convolution (DSGC) approach which is compatible with the tradition...
