摘要:

在本文中,我们介绍了第一个强化学习(RL)的机器人导航方法,利用超声(US)图像作为输入。我们的方法结合了最先进的RL技术,特别是具有内存缓冲区的深度Q网络(DQN)和用于决定何时终止任务的二进制分类器。我们的方法是在内部收集的34名志愿者的数据集上进行训练和评估的,与纯RL和监督学习(SL)技术相比,它的表现要好得多,这突出了RL导航对US引导程序的适用性。在测试我们提出的模型时,我们在5个不同的看不见的模拟环境中从165个不同的起始位置正确导航到骶骨的概率为82.91%。

英文摘要:

In this paper we introduce the first reinforcement learning (RL) based robotic navigation method which utilizes ultrasound (US) images as an input. Our approach combines state-of-the-art RL techniques, specifically deep Q-networks (DQN) with memory buffers and a binary classifier for deciding when to terminate the task. Our method is trained and evaluated on an in-house collected data-set of 34 volunteers and when compared to pure RL and supervised learning (SL) techniques, it performs substantially better, which highlights the suitability of RL navigation for US-guided procedures. When testing our proposed model, we obtained a 82.91% chance of navigating correctly to the sacrum from 165 different starting positions on 5 different unseen simulated environments.
