摘要:

自治系统通常在多个代理的行为由共享的全局状态协调的环境中运行。因此,可靠的估计的全局状态是成功地在多代理设置操作的关键。我们引入代理感知状态估计-一个框架,用于计算间接估计的状态给定的观察其他代理在环境中的行为。我们还介绍了过渡独立的代理意识的状态估计-一类听话的代理意识的状态估计-并表明,它允许推理的速度与环境中的代理数量成线性比例。作为一个例子,我们在完全失去直接观察的情况下对交通灯分类进行建模。通过考虑从多个方向的交通的车辆行为的观察,我们的方法表现出比现有的交通灯只有HMM方法在各种模拟遮挡场景下的真实世界的自动驾驶汽车数据集的准确性更高。

英文摘要:

Autonomous systems often operate in environments where the behavior of multiple agents is coordinated by a shared global state. Reliable estimation of the global state is thus critical for successfully operating in a multi-agent setting. We introduce agent-aware state estimation -- a framework for calculating indirect estimations of state given observations of the behavior of other agents in the environment. We also introduce transition-independent agent-aware state estimation -- a tractable class of agent-aware state estimation -- and show that it allows the speed of inference to scale linearly with the number of agents in the environment. As an example, we model traffic light classification in instances of complete loss of direct observation. By taking into account observations of vehicular behavior from multiple directions of traffic, our approach exhibits accuracy higher than that of existing traffic light-only HMM methods on a real-world autonomous vehicle data set under a variety of simulated occlusion scenarios.
