a. Higher Order Sparse Convolutions in Graph Neural Networks
Graph Neural Networks (GNNs) have been applied to many problems in
computer science. Capturing higher-order relationships between nodes is crucial
to increasing the expressive power of GNNs. We introduce new higher-order
sparse convolution methods based on the Sobolev norm of graph signals.

c. Network Community Detection
This study tackles community detection challenges in network structures by
leveraging the geodesic space. Overcoming the limitations of traditional graph
theoretic algorithms, we explore the methods that employ sparse linear coding
with L1 norm constraint and sparse spectral clustering algorithms to enhance
accuracy in identifying community boundaries.
