Pumping lemmas for weighted automata [PDF]

open access: yesLogical Methods in Computer Science, 2021
We present pumping lemmas for five classes of functions definable by fragments of weighted automata over the min-plus semiring, the max-plus semiring and the semiring of natural numbers. As a corollary we show that the hierarchy of functions definable by

Weighted Automata over Vector Spaces [PDF]

open access: yesInternational Conference on Automata and Formal Languages, 2023
In this paper we deal with three models of weighted automata that take weights in the field of real numbers. The first of these models are classical weighted finite automata, the second one are crisp-deterministic weighted automata, and the third one are

Nested Weighted Automata [PDF]

open access: yes2015 30th Annual ACM/IEEE Symposium on Logic in Computer Science, 2015
Recently there has been a significant effort to handle quantitative properties in formal verification and synthesis. While weighted automata over finite and infinite words provide a natural and flexible framework to express quantitative properties, perhaps surprisingly, some basic system properties such as average response time cannot be expressed ...

Feasability of Learning Weighted Automata on a Semiring [PDF]

open access: yesLogical Methods in Computer Science, 2023
Since the seminal work by Angluin and the introduction of the L*-algorithm, active learning of automata by membership and equivalence queries has been extensively studied to learn various extensions of automata.

Synchronizing weighted automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We introduce two generalizations of synchronizability to automata with transitions weighted in an arbitrary semiring K=(K,+,*,0,1). (or equivalently, to finite sets of matrices in K^nxn.) Let us call a matrix A location-synchronizing if there exists a ...

Pebble Weighted Automata and Weighted Logics [PDF]

open access: yesACM Transactions on Computational Logic, 2014
We introduce new classes of weighted automata on words. Equipped with pebbles, they go beyond the class of recognizable formal power series: they capture weighted first-order logic enriched with a quantitative version of transitive closure. In contrast to previous work, this calculus allows for unrestricted use of existential and universal ...

Containment and Equivalence of Weighted Automata: Probabilistic and Max-Plus Cases [PDF]

open access: yesLanguage and Automata Theory and Applications, 2020
This paper surveys some results regarding decision problems for probabilistic and max-plus automata, such as containment and equivalence. Probabilistic and max-plus automata are part of the general family of weighted automata, whose semantics are maps ...

On Determinism and Unambiguity of Weighted Two-way Automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
In this paper, we first study the conversion of weighted two-way automata to one-way automata. We show that this conversion preserves the unambiguity but does not preserve the determinism.

Bisimulation Metrics for Weighted Automata [PDF]

open access: yesCoRR, 2017
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.
