Abstract

fetched live from OpenAlex

The rise in robot applications across various domains has driven the need for comprehensive environmental understanding. Simultaneous Localization and Mapping (SLAM) is an algorithm that facilitates operations like navigation, and space reconstruction. Deep learning-based SLAM has emerged as a solution to address challenges faced by conventional SLAM algorithms, particularly in dynamic environments and long-scale mapping scenarios. This thesis introduces a novel approach to loop closure detection (LCD) with a real-time graph framework. This modularized, parameter-free system employs features extracted from deep learning-based backbone models. It calculates matching scores, generates a graph structure, exhibiting faster processing times compared to other methods. Furthermore, it explores the integration of graph neural networks (GNN) to improve performance metrics. A supervised offline method incorporates GNN into the LCD process, demonstrating enhanced performance, notably in reducing false positives. This approach marks a significant contribution to the literature, highlighting the potential of GNN in loop closure algorithms.

Full frame distilled prediction

Teacher imitation

Not 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.
