用自动机预测无限词

Prediction of Infinite Words with Automata

Northeastern University(东北大学)

摘要:

在经典的序列预测问题中,预测器从发射器接收一系列值,并试图在下一个值出现之前猜测它。如果存在一个点,在该点之后预测器的所有猜测都是正确的,则预测器控制发射器。在本文中,我们考虑的情况下,预测是一个自动机和发射值是从一个有限的集合;即,所发射的序列是无限的字。我们研究有限自动机,下推自动机,堆栈自动机(下推自动机的推广),和多头有限自动机的预测能力。我们将我们的预测自动机纯周期性的话,最终周期性的话,和多线性的话,描述新的预测算法,掌握这些序列。

英文摘要:

In the classic problem of sequence prediction, a predictor receives a sequence of values from an emitter and tries to guess the next value before it appears. The predictor masters the emitter if there is a point after which all of the predictor's guesses are correct. In this paper we consider the case in which the predictor is an automaton and the emitted values are drawn from a finite set; i.e., the emitted sequence is an infinite word. We examine the predictive capabilities of finite automata, pushdown automata, stack automata (a generalization of pushdown automata), and multihead finite automata. We relate our predicting automata to purely periodic words, ultimately periodic words, and multilinear words, describing novel prediction algorithms for mastering these sequences.
