Abstract

fetched live from OpenAlex

An argument is presented that a two-way relationship between position and visual information can be utilized to improve estimates of vehicle position as well as the interpretation of the surrounding environment. Simulation results for a formulation based on dynamic Bayesian networks illustrate that the belief in vehicle position is influenced by the measured visual features, while the belief in the value of said visual features is in turn influenced by GPS measurements of vehicle position. The weight of these influences, as well as the uncertainty of the resulting state estimates, depends directly upon the rate-of-change of the observed features. This information sharing approach represents a successful integration of these two technologies that leads to more plausible vehicle positioning and visual feature estimation that will be useful for purposes of automated driving and navigation systems.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
