Heterogeneous Sequel-Aware Graph Neural Networks for Sequential Learning
A sequel-aware graph neural network that explicitly models item-series relationships improves next-item recommendation on datasets where sequels are common, but it can underperform a strong baseline when sequel information is sparse.
