Fuzzy finite automata and fuzzy regular expressions with membership values in lattice-ordered monoids

Y Li, W Pedrycz - Fuzzy sets and systems, 2005 - Elsevier
We study fuzzy finite automata in which all fuzzy sets are defined by membership functions
whose codomain forms a lattice-ordered monoid L. For these L-fuzzy finite automata (L-FFA …

A real-coded genetic algorithm for training recurrent neural networks

A Blanco, M Delgado, MC Pegalajar - Neural networks, 2001 - Elsevier
The use of Recurrent Neural Networks is not as extensive as Feedforward Neural Networks.
Training algorithms for Recurrent Neural Networks, based on the error gradient, are very …

On reduced fuzzy multiset finite automata

M Shamsizadeh, MM Zahedi - Soft Computing, 2022 - Springer
This study aimed to examine deterministic FMFA, complete FMFA, and accessible FMFA,
using the definition of fuzzy multiset finite automaton (FMFA). We show that a fuzzy multiset …

Fuzzy tree automata

Z Ésik, G Liu - Fuzzy Sets and Systems, 2007 - Elsevier
In this paper, we map an arbitrary algebra to a completely distributive lattice and define
algebras of fuzzy sets. When the algebra is a term algebra, we obtain fuzzy tree languages …

Fuzzy languages

G Rahonis - Handbook of Weighted Automata, 2009 - Springer
The theory of fuzzy recognizable languages over bounded distributive lattices is presented
as a paradigm of recognizable formal power series. Due to the idempotency properties of …

Construction of a minimal realization and monoid for a fuzzy language: a categorical approach

SP Tiwari, VK Yadav, AK Singh - Journal of Applied Mathematics and …, 2015 - Springer
The purpose of the present work is to construct a minimal deterministic fuzzy automaton and
to provide a minimal monoid representation for a given fuzzy language in a categorical …

Bisimulation of type 2 for BL-general fuzzy automata

M Shamsizadeh, MM Zahedi - Soft Computing, 2019 - Springer
In this note, first, we define bisimulation of type 2 for a basic logic general fuzzy automaton
and show that if there exists a bisimulation of type 2 between two basic logic general fuzzy …

Fuzzy tree language recognizability

S Bozapalidis, OL Bozapalidoy - Fuzzy Sets and Systems, 2010 - Elsevier
A fuzzy tree language with membership grades in an arbitrary set is syntactically
recognizable (s-recognizable) if its syntactic algebra is finite. The equality problem for such …

Fuzzy languages with infinite range accepted by fuzzy automata: Pum** lemma and determinization procedure

JRG de Mendívil, JR Garitagoitia - Fuzzy Sets and Systems, 2014 - Elsevier
The formulation of fuzzy automata allows us to select a great variety of triangular norms.
Depending on the selected triangular norm, a fuzzy automaton can accept a fuzzy language …

Irreducible fuzzy multiset finite automaton

M Shamsizadeh, M Mehdi Zahedi… - The Computer …, 2024 - academic.oup.com
This study aims to investigate the algebraic properties of fuzzy multiset finite automaton
(FMFA), giving a congruence relation. Using the equivalence classes, a minimal accessible …
