Abstract

fetched live from OpenAlex

The two main challenges offered by Simultaneous Localization and Mapping (SLAM) are that of observability and extending state estimation to exploration. This thesis explores and uses solutions to render the SLAM problem observable, by proposing the Reconfigurable Extended Kalman Filter (EKF) that addresses imposing observability, maintaining observability and choice of observability constraints. Additionally, Bayesian theory and Dempster-Shafer theory of evidential reasoning are analyzed, and Occupancy grid based maps based on Dempster-Shafer theory of evidential reasoning are created and analyzed in large environment for their potential use in exploration and obstacle avoidance. Tackling both issues with different algorithms yield better solutions to the challenges offered by robotic exploration, and this is demonstrated through simulation results in representative environments.

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.
