Abstract

fetched live from OpenAlex

Modern data-driven perception systems accomplish excellent performance in a simple, constrained environment but have unreliable detection in real, complex, and challenging weather situations. Therefore, robust perception performance in new and unanticipated domains is a crucial factor for autonomous driving. To this end, this paper proposes a novel robust learning scheme for arbitrary domain perturbations. In this paper, the model robustness is characterized by the anchor data and corresponding various domain shift directions. The robust learning problem is then formulated as a min-max optimization problem conjugated to the constrained exploration space defined by the perturbation model and the semantic parameter. The proposed robustify procedure solves the optimization problem considering the worst-case scenario, which improves the model resilience in multiple domain shift directions, especially for those variations in Cyber-Physical-Social Systems (CPSS).

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.
