On the Impact of Graph Neural Networks in Recommender Systems: A Topological Perspective

Daniele Malitesta, Claudio Pomo, Vito Walter Anelli +3

In recommender systems, user-item interactions can be modeled as a bipartite graph, where user and item nodes are connected by undirected edges. This graph-based view has motivated…
