Abstract
摘要： 随着人工智能领域的快速发展，深度学习在无人驾驶领域中的应用逐渐成熟，但是其中交通标志检测任务作为难点问题仍有很大的改进空间。城市道路下的交通标志检测具有环境复杂、小目标多、目标种类多且数量不平衡的特点，针对这些问题，提出基于Libra R-CNN进行改进的方案。Libra R-CNN目标检测网络是基于平衡提出的，能够较好应对目标种类多及数量不平衡问题，在Libra R-CNN网络的锚框提取样本阶段，使用GA-RPN生成锚框，从而在训练期间产生更精确、更多样化的样本，减少背景影响和小目标不好定位的问题，提高检测准确率。该方法通过试验验证了有效性。试验是在MS COCO 2017和交通标志数据集上进行的。改进后的Libra R-CNN的mAP提高了超2.7个百分点。试验结果表明，改进后的网络相比原有的目标检测网络性能有了显著提升。

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
