Nonlinear spectral clustering with C++ GraphBLAS
Dimosthenis Pasadakis, Olaf Schenk, Verner Vlacic +1
Nonlinear reformulations of the spectral clustering method have gained a lot of recent attention due to their increased numerical benefits and their solid mathematical background.…
Fraud Detection in Cryptocurrency Markets with Spatio-Temporal Graph Neural Networks
Lidia Losavio, Luca Persia, Madan Sathe +1
Technological advancements in cryptocurrency markets have increased accessibility for investors, but concurrently exposed them to the risks of market manipulations. Existing fraud…
Symmetry-breaking symmetry in directed spectral partitioning
Dimosthenis Pasadakis, Raphael S. Steiner, Pál András Papp +2
We break the symmetry in classical spectral bi-partitioning in order to incentivise the alignment of directed cut edges. We use this to generate acyclic bi-partitions and furthermo…
Nonlinear PageRank Problem for Local Graph Partitioning
Costy Kodsi, Dimosthenis Pasadakis
A nonlinear generalisation of the PageRank problem involving the Moore-Penrose inverse of an incidence matrix is developed for local graph partitioning purposes. The Levenberg-Marq…
Multiway -spectral graph cuts on Grassmann manifolds
Dimosthenis Pasadakis, Christie Louis Alappat, Olaf Schenk +1
Nonlinear reformulations of the spectral clustering method have gained a lot of recent attention due to their increased numerical benefits and their solid mathematical background.…
