Abstract  

The research on microscopic diffusion prediction is of great significance for understanding the propagation of information in social networks. To improve the accuracy of information diffusion predictions, an information microscopic diffusion prediction model integrating cascaded frequency domain features is proposed. First, a social graph and an information diffusion hypergraph are constructed separately based on user friendship relationships and historical cascades. Graph convolutional neural networks are utilized to capture user representations in social relationships and forwarding behaviors. Next, Fourier Transform is applied to map the time-domain cascade features to the frequency domain, effectively capturing both short-term fluctuations and long-term trends in the cascade through high-frequency and low-frequency components. Finally, an attention fusion layer is designed to generate a more expressive user representation, effectively addressing the issues of feature redundancy and information loss. Thus, the performance of the proposed model is further optimized. Experiments on four public datasets show the proposed model improves Hits@K and mAP@K, demonstrating the effectiveness of itself.
