Agent信念与决策的概率模型

Probabilistic Models for Agents' Beliefs and Decisions

Stanford University(斯坦福大学)

Brian Milch, Daphne Koller

摘要:

智能系统的许多应用需要对领域中代理的心理状态进行推理。我们可能想推理一个智能体的信念,包括关于其他智能体的信念;我们也可能想推理一个智能体的偏好,以及他的信念和偏好如何与他的行为相关。我们定义了一个概率认知逻辑(PEL),其中的信念语句给出了一个正式的语义,并提供了一个算法,断言和查询的PEL公式在贝叶斯网络。然后,我们将展示如何通过将代理的决策过程建模为影响图并假设他的行为是理性的来推理代理的行为。然后,PEL可以用于从代理的观察到的动作推理到关于域的其他方面的结论,包括未观察到的域变量和代理的精神状态。

英文摘要:

Many applications of intelligent systems require reasoning about the mental states of agents in the domain. We may want to reason about an agent's beliefs, including beliefs about other agents; we may also want to reason about an agent's preferences, and how his beliefs and preferences relate to his behavior. We define a probabilistic epistemic logic (PEL) in which belief statements are given a formal semantics, and provide an algorithm for asserting and querying PEL formulas in Bayesian networks. We then show how to reason about an agent's behavior by modeling his decision process as an influence diagram and assuming that he behaves rationally. PEL can then be used for reasoning from an agent's observed actions to conclusions about other aspects of the domain, including unobserved domain variables and the agent's mental states.
