论文摘要
实际上，寻求帮助通常比搜索整个空间更有效地找到一个未知位置的对象。我们提出了一个学习框架，该框架使代理商能够在此类具体的视觉导航任务中积极寻求帮助，在这种情况下，反馈将其视为目标的位置。为了模仿老师可能并不总是在场的现实情况，我们提出了一项培训课程，而反馈并不总是可用。我们制定了一个不确定性衡量目标所在的位置，并使用经验结果表明，通过这种方法，代理商可以有效地寻求帮助，同时在没有反馈时保持健壮。
In reality, it is often more efficient to ask for help than to search the entire space to find an object with an unknown location. We present a learning framework that enables an agent to actively ask for help in such embodied visual navigation tasks, where the feedback informs the agent of where the goal is in its view. To emulate the real-world scenario that a teacher may not always be present, we propose a training curriculum where feedback is not always available. We formulate an uncertainty measure of where the goal is and use empirical results to show that through this approach, the agent learns to ask for help effectively while remaining robust when feedback is not available.
