Speaker: Yuan Cao Title: Benign Overfitting in Two-layer Convolutional Neural Networks Abstract: Modern neural networks often have great expressive power and can be trained to overfit the training data, while still achieving a good test performance. This phenomenon is referred to as “benign ...
Diffusion Convolutional Neural Network (DCNN) 扩散卷积神经网络 扩散卷积神经网络将图卷积视为扩散过程。它假设信息以一定的转移概率从一个节点转移到其相邻节点之一,使得信息分布在几轮后达到平衡。 DCNN 将扩散图卷积定义为: \mathbf{H}^{(k)}=f\left(\mathbf{W}^{(k)} \odot \mathbf{P}^{k} \mathbf...
论文地址:https://arxiv.org/pdf/1409.2329.pdf 一、RNN简介 RNN(Recurrent Neural Network)是一类用于处理序列数据的神经网络。神经网络包含输入层、隐层、输出层,通过**函数控制输出,层与层之间通过权值连接。下图一个标准的RNN结构图,图中每个箭头代表做一次变换,也就是说箭头连接带有权值。左侧是折叠起来的样子...

Based on CNNs and graph embedding, graph neural networks (GNNs) are proposed to collectively aggregate information from graph structure. Thus they can model input and/or output consisting of elements and their dependency. Further, graph neural network can simultaneously model the diffusion process on...
