Abstract
Visual SLAM systems are concurrent, performance-critical systems that respond to real-time environmental conditions and are frequently deployed on resource-constrained hardware. Previous work has identified three interconnected systems challenges to building consistent, accurate, and robust SLAM systems— timeliness , concurrency , and context awareness . In this article, we analyze three popular, state-of-the-art frameworks with varying system designs and optimization techniques, and we quantify the extent to which they are affected by the aforementioned system challenges. We find that all SLAM systems must balance the interconnected nature of timeliness and accuracy, and different system designs and optimization techniques uniquely address this tension. Global-map-based SLAM systems typically achieve the best performance but suffer in resource-constrained scenarios with increased concurrency . Across all SLAM systems, incorporating context awareness into decision-making would mitigate the impact of timeliness and concurrency on accuracy in resource-constrained scenarios.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
