Abstract
This paper describes a general formulation for vehicle position estimation within a road network using visual features from a camera system and a priori knowledge in the form of Geographic Information System (GIS) data. The proposed approach consists of two parts. First, features of the environment are detected by the vision system while corresponding features are extracted from the GIS, which can be considered a system's internal model of the environment. Second, vehicle position is tracked over time using an extended Kalman filtering (EKF) scheme in which visual feature estimates are compared to features extracted from the GIS world model. Simulation results provide a visual illustration of the theoretical finding that uncertainty in vehicle position is reduced by the observation of features changing continuously with vehicle position. This work is applicable for autonomous navigation systems (which must observe the vehicle environment) and as a complement to satellite positioning methods.

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
