关于加权自动机的等价性和极小化的注记

Notes on Equivalence and Minimization of Weighted Automata

Stefan Kiefer

摘要:

这组笔记重新证明了加权自动机(域上,也称为多重自动机)的已知结果。文本提供了一个统一的观点,定理和证明,已经出现在文献中几十年来,并在不同的风格和上下文写的。这里报告的结果都不是新的。内容围绕等效和最小化的基本原理,重点是算法方面。介绍是简约的。没有试图激发材料。从线性代数的角度研究了加权自动机。因此,证明,这意味着是简洁的,但完整的,几乎是自给自足的,主要依赖于初等线性代数。

英文摘要:

This set of notes re-proves known results on weighted automata (over a field, also known as multiplicity automata). The text offers a unified view on theorems and proofs that have appeared in the literature over decades and were written in different styles and contexts. None of the results reported here are claimed to be new. The content centres around fundamentals of equivalence and minimization, with an emphasis on algorithmic aspects. The presentation is minimalistic. No attempt has been made to motivate the material. Weighted automata are viewed from a linear-algebra angle. As a consequence, the proofs, which are meant to be succinct, but complete and almost self-contained, rely mainly on elementary linear algebra.
