Abstract

fetched live from OpenAlex

Vehicle motion prediction aims to regress a continuous future trajectory from past motion data for all agents in the scene. However, not all future trajectories are viable for each agent. Vehicle trajectories are often limited by factors such as current vehicle dynamics, an agent’s location in the scene, and legal traffic maneuvers. We look to use this idea and frame the vehicle motion prediction problem as a classification problem across a set of trajectories that are ensured to be viable. While other methods typically only consider vehicle dynamics, we look to also explicitly factor in lane geometries and traffic rules as constraints in our trajectory set generation. Although we are unable to achieve similar performance to SOTA, we show that even with minimal training data, this approach allows for generalization to completely new scenes with no retraining and minimal performance loss.

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.

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.
