Despite the popularity of Collaborative Filtering (CF), CF-based methods are haunted by the cold-start problem, which has a significantly negative impact on users' experiences with Recommender Systems (RS. [] Key Method Then, we propose a new spectral convolution operation directly performing in the spectral domain, where not only the proximity information of a graph but also the connectivity information hidden in the graph are revealed.

LECF: recommendation via learnable edge collaborative filtering

This paper model an interaction between user and item as an edge and proposes a novel CF framework, called learnable edge collaborative filtering (LECF), which predicts the existence probability of an edge based on the connections among edges and is able to capture the complex relationship in data.

Spectrum-enhanced Pairwise Learning to Rank

Spectral features extracted from two hypergraph structures of the purchase records are introduced and used to model the users' preference and items' properties by incorporating them into a Matrix Factorization (MF) model, which outperform several state-of-the-art models significantly.
