Introduction to Graph Neural Network翻译-第五章 图卷积网络 5. 图卷积网络 在本章中,我们将讨论图卷积网络(GCNs),其目的是将卷积推广到图域。 由于卷积神经网络(CNNs)在深度学习领域取得了巨大的成功,因此在图上定义卷积运算是非常直观的。 在这个方向上的进展通常分为频谱方法和空间方法。 由于在每个方向上都...

In the previous sections, we got acquainted with the architecture of a fully connected perceptron and constructed our first neural network model. We tested it in various modes, received our first results, and gained our first experience. However, the fully connected neural layers used in the perc...
Neural networks are able to "learn" by adjusting the strengths of these connections until they can approximate a function that computes the proper output for a given input pattern. In this article I'll examine one of the most common types of neural networks, the feed-fo...
1.2 The definition of neural networks 人工神经网络的定义 Neural network is a concept under the realm of machine learning, which is a type of algorithm used to analyze data. It is a fruit of bionics, which means that the structure of human being's neural networks(e.g. neuron, axon, dendr...
