SGS-GNN: A Supervised Graph Sparsification method for Graph Neural Networks

Siddhartha Shankar Das, Naheed Anjum Arafat, Muftiqur Rahman +3

We propose SGS-GNN, a novel supervised graph sparsifier that learns the sampling probability distribution of edges and samples sparse subgraphs of a user-specified size to reduce t…

Parallel Algorithms for Median Consensus Clustering in Complex Networks

Md Taufique Hussain, Mahantesh Halappanavar, Samrat Chatterjee +3

We develop an algorithm that finds the consensus of many different clustering solutions of a graph. We formulate the problem as a median set partitioning problem and propose a gree…

Picasso: Memory-Efficient Graph Coloring Using Palettes With Applications in Quantum Computing

S M Ferdous, Reece Neff, Bo Peng +6

A coloring of a graph is an assignment of colors to vertices such that no two neighboring vertices have the same color. The need for memory-efficient coloring algorithms is motivat…

Semi-Supervised Learning of Dynamical Systems with Neural Ordinary Differential Equations: A Teacher-Student Model Approach

Yu Wang, Yuxuan Yin, Karthik Somayaji Nanjangud Suryanarayana +5

Modeling dynamical systems is crucial for a wide range of tasks, but it remains challenging due to complex nonlinear dynamics, limited observations, or lack of prior knowledge. Rec…
