VSA-OGM: The Neuro-Symbolic Advantage
VSA-OGM introduces a novel neuro-symbolic framework for Occupancy Grid Mapping (OGM), combining the interpretability and stability of traditional methods with the computational efficiency of neural networks. This approach uses Vector Symbolic Architectures (VSA) to efficiently encode and process semantic and spatial information, crucial for real-time robotic systems operating under strict computational and latency constraints.
Unlike traditional methods that rely on dense statistical calculations or neural methods that use deep learning for black-box probabilistic inference, VSA-OGM provides a transparent and robust solution. It eliminates the need for domain-specific pretraining, making it highly adaptable and suitable for safety-critical applications.
Unprecedented Efficiency & Accuracy
VSA-OGM demonstrates superior performance across multiple datasets, achieving accuracy comparable to state-of-the-art traditional methods while drastically reducing computational overhead.

Case Study: Real-World Performance on Intel Map Dataset
The Intel Map dataset, a widely-used real-world benchmark, highlights VSA-OGM's capabilities in practical scenarios. On this dataset, VSA-OGM achieved an AUC score of 0.95, demonstrating high accuracy comparable to traditional methods. Crucially, it delivered a significant 45x latency reduction (510 ms vs. 22.35 s for BHM-Full) and an astounding 392x memory reduction (16.3 MB vs. 6400 MB for BHM-Full) at a 0.2m resolution.
These results underscore VSA-OGM's potential for efficient, accurate, and real-time occupancy grid mapping in complex, real-world autonomous systems, proving its readiness for deployment in environments with strict computational and latency constraints.
