Abstract
En 中文
In the past, many methods have been proposed for the inference of probabilistic and non-probabilistic finite state automata from positive examples of their behaviour. In this paper, we introduce a search method guided by the information-theoretic Minimum Message Length principle to infer Probabilistic Finite State Automata (PFSA).(1) The method is a beam search technique that searches for the best PFSA that accounts for a given dataset. Results of testing this method against some earlier algorithms are presented. A simulated annealing version of the beam search algorithm is also described as ongoing research in the area.
