Convolution plays a key role inconvolutional neural networks(CNNs). CNNs are a type of deep network commonly used to analyze images. CNNs eliminate the need for manual feature extraction, which is why they work very well for complex problems such as image classification and medical image analys...
在卷积神经网络(Convolutional Neural Network,简称 CNN)中,卷积操作用于提取图像或其他数据的特征,从而实现分类、回归等任务。卷积的基本思想是将一个函数(信号或图像)与一个卷积核(一个小的函数)进行组合 机器学习中的卷积(Convolution)是一种特殊的数学运算,主要应用于信号处理和图像处理领域。在卷积神经网络(Convolut...

In the bustling streets, the human brain can quickly capture important details, such as a child suddenly dashing out or a car speeding towards. However, traditional AI, especially the widely used Convolutional Neural Network (CNN), is somewhat "clumsy". They usually use square "filters" of fix...
消息传递网络(Message Passing Neural Network) 消息传递网络(MPNN)[1] 是由Google科学家提出的一种模型。严格意义上讲,MPNN不是一种具体的模型,而是一种空域卷积的形式化框架。它将空域卷积分解为两个过程:消息传递与状态更新操作,分别由M_{l}(\cdot)和U_{l}(\cdot)函数完成。将结点v的特征\mathbf{x}_v作...
