感悟 看完图卷积一代.二代,深感图卷积的强大,刚开始接触图卷积的时候完全不懂为什么要使用拉普拉斯矩阵( $L=D-W$),主要是其背后的物理意义.通过借鉴前辈们的论文.博客.评论逐渐对图卷积有了一定的了解,作为一个刚上研的博士生,深感得对图神经网络进行一个系统的学习. 本篇论文得感谢论文 David I Shuman 作者及博主:纯牛奶爱酸牛奶 Paper Information Authors:D. Shuman, S. Narang, P. Frossard, Antonio Ortega,…

诚心给大家推荐一本讲信号处理的好书<Digital Signal Processing - A Practical Guide for Engineers and Scientists>[美]Steven W.Smith,中文版叫<实用数字信号处理-从原理到应用>张瑞峰译,人民邮电出版社. 这本书最大的特点是"多图多字少公式",把数字信号处理(主要是滤波器)的原理和特性讲得很透彻很生动,平实易懂,很少推公式,插图和代码占了这本书的一半.真心想弄懂信号滤波器(包括…

Maybe you were asking if there is some kind of design tool allowing to convert an IIR filter into an FIR filter automatically. There is no such a program. IIRs and FIRs have fundamentally different characteristics. If you are just interested in desig…
