We consider matrix completion for recommender systems from the point of view of link prediction on graphs. Interaction data such as movie ratings can be represented by a bipartite user-item graph with ...
Abstract: Graph spectral filtering relies on a representation matrix to define the frequency-domain transformations. Conventional approaches use fixed graph representations, which limit their ...
Abstract: The extraction and filtering of electric network frequency (ENF) is significant for verifying the authenticity of digital audio. However, there are many challenges in accurately extracting ...
