Abstract
In end-to-end autonomous driving, current sensor fusion and navigational control techniques used by imitation learning algorithms are insufficient in challenging scenarios involving multiple dynamic agents and result in poor driving capabilities. To tackle this issue, we introduce DMFuser, a transformer-based algorithm that employs knowledge distillation between multi-task student and single-task teachers and combines attention and convolutions to fuse multiple RGB-D camera representations to produce vehicular navigational commands (throttle, steering and brake). Our model incorporates two modules. The first module, perception, encodes data from RGB-D cameras for tasks like semantic segmentation, semantic depth cloud (SDC) mapping, and traffic light state recognition. To enhance feature extraction and fusion from both RGB and depth sources, we harness local and global capabilities of convolution and transformer modules. We employ an attention-CNN fusion structure to effectively learn and fuse RGB and SDC map features. Subsequently, the control module decodes these features along with supplementary data, containing environment’s static and dynamic information, to predict waypoints and vehicular control actions. We evaluate the model and conduct a comparative analysis, in various scenarios, weather conditions, and traffic situations, spanning from normal to adversarial in the CARLA simulator. We achieve better or comparable results in term of driving score (DS) and other metrics with respect to our baselines. Also, our ablation studies demonstrate the effectiveness of our contributions to improve the driving skills.

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
