摘要:

在这项工作中,我们介绍了一个最近开发的早期分类机制,以卫星为基础的农业监测。它通过基于先前看到的信息的额外停止概率来增强现有的分类模型。该机制是端到端可训练的,并且仅从观察到的卫星数据得出其停止决策。我们在欧洲中部的实地包裹,有足够的地面实况数据可用于经验评估的结果与当地的物候信息从当局。我们观察到,配备了这种早期分类机制的递归神经网络能够在营养期结束之前区分许多作物类型。此外,我们将这些停止时间与评估的地面实况信息相关联,并看到分类时间与观察到的植物物候的特征事件相关。

英文摘要:

In this work, we introduce a recently developed early classification mechanism to satellite-based agricultural monitoring. It augments existing classification models by an additional stopping probability based on the previously seen information. This mechanism is end-to-end trainable and derives its stopping decision solely from the observed satellite data. We show results on field parcels in central Europe where sufficient ground truth data is available for an empiric evaluation of the results with local phenological information obtained from authorities. We observe that the recurrent neural network outfitted with this early classification mechanism was able to distinguish the many of the crop types before the end of the vegetative period. Further, we associated these stopping times with evaluated ground truth information and saw that the times of classification were related to characteristic events of the observed plants' phenology.
