Abstract
In the application of visual navigation, submap-based visual simultaneous localization and mapping (VSLAM) has become one of the most robust monocular solutions in recent years, which is able to resume tracking by multisubmap maintenance and merging. However, due to the lack of long-term data association between submaps, global consistency cannot be guaranteed in the existing work, especially in situations without loop-closure. Considering the fact that not all the submap have to be built in realtime, we propose a VSLAM system with realtime and nonrealtime hybrid style, RUMI-SLAM. Inspired by the rumination of mammalians that processes food in various stomaches and absorbs it in one stomach, RUMI-SLAM performs asynchronous submap building and centralized submap management. Building additional submaps in parallel leads to enriched mapping elements and enhanced data association across submaps. The experimental results demonstrate the superiority of RUMI-SLAM over the existing VSLAM systems, especially the robustness to challenging situations. We also provide real-robot experiments to demonstrate our RUMI-SLAM in the application of visual navigation. Our study provides a novel asynchronous submap-based VSLAM framework, which achieves globally consistent submap merging without the requirement of loop-closure.

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
