Beyond Classical Diffusion: Ballistic Graph Neural Network
This paper presents the ballistic graph neural network.Ballistic graph neural network tackles the weight distribution from a transportation perspective and has many different properties comparing to the traditional graph neural network pipeline.The ballistic graph neural network does not require to calculate any eigenvalue.The filters propagate exponentially faster comparing to traditional graph neural network.We use a perturbed coin operator to perturb and optimize the diffusion rate.Our results show that by selecting the diffusion speed, the network can reach a similar accuracy with fewer parameters.We also show the perturbed filters act as better representations comparing to pure ballistic ones.We provide a new perspective of training graph neural network, by adjusting the diffusion rate, the neural networks performance can be improved.
A new perspective on how to collect the correlation between nodes based on diffusion properties.A new diffusion operation for graph neural networks that does not require eigenvalue calculation and can propagate exponentially faster compared to traditional graph neural networks.The paper proposes to cope with the speed of diffusion problem by introducing ballistic walk.
