新的交叉验证方法提高了 AI 水果货架期预测的准确性

研究人员开发了一种新方法来评估从图像预测水果剩余货架期的 AI 模型的准确性。使用 Hass 牛油果成熟度数据集,他们发现样本级交叉验证(确保同一水果的图像不用于训练和测试)比观察级拆分提供了更现实的性能估计。这种方法显示出更高的错误率,样本不重叠的交叉验证产生的平均 RMSE 为 3.12 天,而观察级拆分的平均 RMSE 为 2.37 天。该研究还将 MobileNetV3-Small 等轻量级模型与 ResNet-18 等较重模型进行了比较,发现准确性相当,但较小模型的吞吐量显著提高,并使用 Grad-CAM 分析了视觉归因差异。 AI

影响 这项研究通过提高模型评估标准,有望为供应链管理和减少食物浪费带来更可靠的 AI 工具。

    Beyond Group Splits: Specimen-Level Cross-Validation and Visual Attribution for Remaining-Shelf-Life Regression in Climacteric Fruit

    arXiv:2610.09726v1 Announce Type: new Abstract: Estimating remaining shelf life (RSL) from images could provide affordable decision support for perishable produce, but evaluation protocols can substantially affect reported performance when repeated images are available from the s…
