摘要:

准确定位并导航至特定物体的能力,对于在现实世界中运行并与物体交互以完成任务的具身智能体而言是一项关键能力。此类物体导航任务通常需要在带有物体标注的视觉环境中进行大规模训练,而这对于未知环境中的新物体泛化能力较差。本文提出了一种新颖的零样本物体导航方法——软常识约束探索(ESC),该方法将预训练模型中的常识知识迁移到开放世界物体导航中,无需任何导航经验,也无需在视觉环境中进行任何其他训练。首先,ESC利用预训练的视觉-语言模型进行基于提示的开放世界定位,并利用预训练的常识语言模型进行房间和物体推理。然后,ESC通过将常识知识建模为软逻辑谓词,将其转换为导航动作,以实现高效探索。在MP3D、HM3D和RoboTHOR基准上的大量实验表明,我们的ESC方法显著优于基线方法,并在零样本物体导航方面取得了新的最先进结果(例如,在MP3D上相对成功率比CoW提高了288%)。

英文摘要:

The ability to accurately locate and navigate to a specific object is a crucial capability for embodied agents that operate in the real world and interact with objects to complete tasks. Such object navigation tasks usually require large-scale training in visual environments with labeled objects, which generalizes poorly to novel objects in unknown environments. In this work, we present a novel zero-shot object navigation method, Exploration with Soft Commonsense constraints (ESC), that transfers commonsense knowledge in pre-trained models to open-world object navigation without any navigation experience nor any other training on the visual environments. First, ESC leverages a pre-trained vision and language model for open-world prompt-based grounding and a pre-trained commonsense language model for room and object reasoning. Then ESC converts commonsense knowledge into navigation actions by modeling it as soft logic predicates for efficient exploration. Extensive experiments on MP3D, HM3D, and RoboTHOR benchmarks show that our ESC method improves significantly over baselines, and achieves new state-of-the-art results for zero-shot object navigation (e.g., 288% relative Success Rate improvement than CoW on MP3D).
