AI总结:

针对无人机等待计算结果或提前飞往下一兴趣点的决策难题,本文提出基于历史任务经验的学习方法,在稳定与时变动作概率场景下均优于静态策略,最高提升25.8%。

摘要:

多旋翼无人机正成为多个应用领域中的关键平台,能够实现精确的现场传感和/或执行。我们关注这样一种情形:无人机必须处理传感器数据,以便根据处理结果决定是否需要执行某些额外动作,例如更精确的传感或某种形式的执行。一方面,如果最终表明不需要进一步动作,等待计算完成可能会浪费时间。另一方面,如果无人机在计算结束前就开始飞向下一个兴趣点,而此时又需要采取某些动作,它就可能不得不返回前一个点。本文提出一种学习方法,使无人机能够基于从以往任务中收集的经验,就在否等待计算结果做出知情决策。通过广泛评估,我们表明:在合理配置下,所提出的方法在多种不同场景中均优于若干静态策略,性能提升最高达25.8%;这些场景既包括某个兴趣点需要采取动作的概率保持稳定的情形,也包括该概率随时间变化的情形。

英文摘要:

Multicopter drones are becoming a key platform in several application domains, enabling precise on-the-spot sensing and/or actuation. We focus on the case where the drone must process the sensor data in order to decide, depending on the outcome, whether it needs to perform some additional action, e.g., more accurate sensing or some form of actuation. On the one hand, waiting for the computation to complete may waste time, if it turns out that no further action is needed. On the other hand, if the drone starts moving toward the next point of interest before the computation ends, it may need to return back to the previous point, if some action needs to be taken. In this paper, we propose a learning approach that enables the drone to take informed decisions about whether to wait for the result of the computation (or not), based on past experience gathered from previous missions. Through an extensive evaluation, we show that the proposed approach, when properly configured, outperforms several static policies, up to 25.8%, over a wide variety of different scenarios where the probability of some action being required at a given point of interest remains stable as well as for scenarios where this probability varies in time.
