Abstract
摘要： 针对现有EfficientNet模型应用于沥青路面状态分类时，卷积操作易导致高层特征信息丢失问题，在现有EfficientNet模型的深层结构中引入一种双注意力机制，包含通道注意力模块和位置注意力模块，借助Sigmoid线性单元（Sigmoid linear unit，SiLU）激活函数和余弦学习率衰减策略，提出一种融合双注意力机制EfficientNet （Dual attention network based on EfficientNet，DAEfficientNet）的沥青路面状态分类方法。首先，建立不同天气下5种沥青路面共5 938张图像作为数据集，积雪样本来自开源数据集（Canadian adverse driving conditions dataset，CADCD）。然后，对所提出模型进行训练，并得到沥青路面图像分类结果。最后，利用准确率（Accuracy）、精确率（Precision）、召回率（Recall）、F1 score和特异度（Specificity），将所提出模型与其他现有卷积神经网络模型进行分类效果对比分析。试验结果表明：所提出模型优于其他对比模型，能准确、有效地对不同天气下的沥青路面状态进行分类。

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
