AI总结:

本文提出一种基于事实概率向量的目标识别方法,通过将观察事实与预期概率映射到实向量空间计算启发式值,并验证了近似概率方法,在降低计算复杂度的同时提升了识别精度。

摘要:

我们提出了一种新的目标识别方法,该方法涉及将观察到的事实与其预期概率进行比较。这些概率取决于指定的目标 g 和初始状态 s0。我们的方法将这些概率和观察到的事实映射到实向量空间中,以计算潜在目标的启发式值。这些值估计了给定目标是观察到的智能体真实目标的可能性。由于获取观察序列中观察到的事实的精确预期概率在实践中通常不可行,我们提出并经验性地验证了一种近似这些概率的方法。我们的经验性结果表明,与最先进的技术相比,所提出的方法提供了更高的目标识别精度,同时降低了计算复杂度。

英文摘要:

We present a new approach to goal recognition that involves comparing observed facts with their expected probabilities. These probabilities depend on a specified goal g and initial state s0. Our method maps these probabilities and observed facts into a real vector space to compute heuristic values for potential goals. These values estimate the likelihood of a given goal being the true objective of the observed agent. As obtaining exact expected probabilities for observed facts in an observation sequence is often practically infeasible, we propose and empirically validate a method for approximating these probabilities. Our empirical results show that the proposed approach offers improved goal recognition precision compared to state-of-the-art techniques while reducing computational complexity.
