Scalable Multi-Task Learning R-CNN for Object Detection in Autonomous Driving
Bibliographic record
Abstract
Multi-task learning (MTL) is a rapidly growing field in the world of autonomous vehicles, particularly in the area of computer vision. Autonomous vehicles are heavily reliant on computer vision technology for tasks such as object detection, object segmentation, and object tracking. The complexity of sensor data and the multiple tasks involved in autonomous driving can make it challenging to design effective systems. MTL addresses these challenges by training a single model to perform multiple tasks simultaneously, utilizing shared representations to learn common concepts between a group of related tasks, and improving data efficiency. In this paper, we propose a scalable MTL system for object detection that can be used to construct any MTL network with different scales and shapes. The proposed system is an extension of the Mask R-CNN. It is designed to overcome the limitations of learning multiple objects in multi-label learning. We have a typical network and evaluated its performance on the Berkeley Deep Drive 100KBDD100k dataset. The experimental results demonstrate that the proposed MTL network outperforms a base single-task network, Mask RCNN, in terms of mean average precision at 50 (mAP50). Furthermore, we have also conducted a comparison with the existing representative approaches.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
