论文摘要
随着跨领域的机器人在共享环境中开始与人类合作，使他们能够推理人类意图的算法对于实现安全的相互作用很重要。在我们的工作中，我们通过预测动态环境中的轨迹的问题来研究人类的意图。我们探索导航准则相对严格定义但在其物理环境中没有明确标记的域。我们假设在这些领域内，代理人倾向于表现出短期运动模式，这些模式揭示了与代理人的一般方向，中间目标和运动规则相关的上下文信息，例如社会行为。从这种直觉中，我们提出了社交patternn，这是一种复发，多模式轨迹预测的算法，利用运动模式来编码上述上下文。我们的方法通过学习预测短期运动模式来指导长期轨迹预测。然后，它从模式中提取次目标信息，并将其汇总为社会环境。我们评估了跨三个领域的方法：人类人群，体育中的人类和终端领域的载人飞机，以实现最先进的表现。
As robots across domains start collaborating with humans in shared environments, algorithms that enable them to reason over human intent are important to achieve safe interplay. In our work, we study human intent through the problem of predicting trajectories in dynamic environments. We explore domains where navigation guidelines are relatively strictly defined but not clearly marked in their physical environments. We hypothesize that within these domains, agents tend to exhibit short-term motion patterns that reveal context information related to the agent's general direction, intermediate goals and rules of motion, e.g., social behavior. From this intuition, we propose Social-PatteRNN, an algorithm for recurrent, multi-modal trajectory prediction that exploits motion patterns to encode the aforesaid contexts. Our approach guides long-term trajectory prediction by learning to predict short-term motion patterns. It then extracts sub-goal information from the patterns and aggregates it as social context. We assess our approach across three domains: humans crowds, humans in sports and manned aircraft in terminal airspace, achieving state-of-the-art performance.
