Columnar-Embedder: A Biologically Inspired Cortical Architecture for Binary Sparse Distributed Graph Representations
Mohamed Abidalrekab, Dan Hammerstrom
Finding a representative description of graph entities that captures their structural roles and homophily is a challenging goal for graph embedding techniques due to the non-Euclid…

SuperiorGAT: Graph Attention Networks for Sparse LiDAR Point Cloud Reconstruction in Autonomous Systems
Khalfalla Awedat, Mohamed Abidalrekab, Gurcan Comert +1
LiDAR-based perception in autonomous systems is constrained by fixed vertical beam resolution and further compromised by beam dropout resulting from environmental occlusions. This…

A Graph Attention Network-Based Framework for Reconstructing Missing LiDAR Beams
Khalfalla Awedat, Mohamed Abidalrekab, Mohammad El-Yabroudi
Vertical beam dropout in spinning LiDAR sensors triggered by hardware aging, dust, snow, fog, or bright reflections removes entire vertical slices from the point cloud and severely…
