Kolmogorov Arnold Graph Convolutional Networks (KA-GCN’s)

Introduction

The fusion of graph neural networks with advanced mathematical transformations has given rise to many innovative models in the field of deep learning. This is what lead me to create such a model, this is the Kolmogorov Arnold Graph Convolutional Network (KA-GCN).

This model leverages the Kolmogorov-Arnold representation theorem and integrates it with Graph Convolutional Networks (GCNs) and Graph Attention Networks (GATs) to classify complex image datasets like CIFAR-10. This blog will delve into the math, the code, and the science behind KA-GCN, providing a detailed walkthrough.

The Kolmogorov-Arnold Representation Theorem

The Kolmogorov-Arnold representation theorem is a result in functional analysis that states any multivariable continuous function can be represented as a finite sum of continuous functions of one variable and a single function of two variables. Specifically, the theorem states:

Graph Convolutional Networks (GCNs)

GCNs extend traditional convolutional networks to graph-structured data. Instead of using regular grid-based convolutions, GCNs perform convolution operations on nodes of a graph, considering the connectivity structure…
