Multimodal Higher-Order Brain Networks: A Topological Signal Processing Perspective
Breno C. Bispo, Stefania Sardellitti, Juliano B. Lima +1
Brain connectomics is still largely dominated by pairwise-based models, such as graphs, which cannot represent circulatory or higher-order functional interactions. In this paper, w…
Topological Signal Processing Over Cell MultiComplexes Via Cross-Laplacian Operators
Stefania Sardellitti, Breno C. Bispo, Fernando A. N. Santos +1
One of the key challenges in many research fields is uncovering how different interconnected systems interact within complex networks, typically represented as multi-layer networks…
Learning Higher-Order Interactions in Brain Networks via Topological Signal Processing
Breno C. Bispo, Stefania Sardellitti, Fernando A. N. Santos +1
Our goal in this paper is to leverage the potential of the topological signal processing (TSP) framework for analyzing brain networks. Representing brain data as signals over simpl…
Cross-Laplacians Based Topological Signal Processing over Cell MultiComplexes
Stefania Sardellitti, Breno C. Bispo, Fernando A. N. Santos +1
The study of the interactions among different types of interconnected systems in complex networks has attracted significant interest across many research fields. However, effective…
