加权自动机的互模拟算法

Bisimulation Metrics for Weighted Automata

Borja Balle, Pascale Gourdeau, Prakash Panangaden

摘要:

我们开发了一个新的互模拟(伪)度量加权有限自动机(WFA),推广Boreale的线性互模拟关系。我们的度量是由WFA的状态空间上的正态性引起的。我们的发展是基于线性算子集的谱性质。特别是,WFA的过渡矩阵的联合谱半径起着核心作用。我们还研究了互模拟伪度量的连续性,建立了计算度量的不可判定性结果,并给出了加权自动机谱学习的应用的初步帐户。

英文摘要:

We develop a new bisimulation (pseudo)metric for weighted finite automata (WFA) that generalizes Boreale's linear bisimulation relation. Our metrics are induced by seminorms on the state space of WFA. Our development is based on spectral properties of sets of linear operators. In particular, the joint spectral radius of the transition matrices of WFA plays a central role. We also study continuity properties of the bisimulation pseudometric, establish an undecidability result for computing the metric, and give a preliminary account of applications to spectral learning of weighted automata.
