Abstract

fetched live from OpenAlex

This thesis proposes an adaptive visual-inertial loosely-coupled sensor fusion method that uses an Error State Kalman Filter (ESKF) and Fuzzy Logic Controller (FLC). The method applies to GPS denied zones. In previous attempts, researchers either tried to tune the Kalman Filter in the most precise way possible, i.e., using the Genetic Algorithm (GA) to tune the Kalman Filter, or make an adaptive Kalman Filter to prevent the divergence problem from happening. This work aims to tune the Kalman Filter and makes it adaptive to overcome the disadvantages of previous methods and minimize the error of the estimated trajectories obtained by the Kalman Filter. The fuzzy system is trained via the Particle Swarm Optimization (PSO) algorithm to achieve this goal. A comparison is held between our tuned Kalman Filter, our adaptive system, and other methods previously used by other researchers. The results show that the proposed adaptive Kalman Filter improves the accuracy and outperforms other methods of tuning Kalman Filters. In addition, our proposed approach outperforms the conventional Extended Kalman Filter (EKF) methods.

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.
