Forecasting seasonal time series with computational intelligence: On recent methods and the potential of their combinations

M Štěpnička, P Cortez, JP Donate… - Expert Systems with …, 2013 - Elsevier
Accurate time series forecasting is a key issue to support individual and organizational
decision making. In this paper, we introduce novel methods for multi-step seasonal time …

F-transform with parametric generalized fuzzy partitions

L Stefanini - Fuzzy Sets and Systems, 2011 - Elsevier
The fuzzy transform (F-transform) has some interesting properties that allow its use in curve
fitting and smoothing. We suggest the following:(a) a generalization of fuzzy partitions for the …

On the relationship among F-transform, fuzzy rough set and fuzzy topology

I Perfilieva, AP Singh, SP Tiwari - Soft Computing, 2017 - Springer
The objective of this work is to associate the concepts of fuzzy rough sets and fuzzy
topologies/co-topologies with the F-transforms. The notions of the direct F^ ↑ F↑ and F^ ↓ …

Finitary solvability conditions for systems of fuzzy relation equations

I Perfilieva - Information Sciences, 2013 - Elsevier
In this paper, we consider the problem of solving systems of fuzzy relation equations. Two
types of these systems with different compositions are considered and processed …

A linguistic approach to time series modeling with the help of F-transform

M Štěpnička, A Dvořák, V Pavliska, L Vavříčková - Fuzzy sets and systems, 2011 - Elsevier
In this paper, we describe an approach to modeling and forecasting time series that uses the
theory of evaluative linguistic expressions, fuzzy/linguistic IF–THEN rules and the fuzzy …

Approximation properties of fuzzy transforms

B Bede, IJ Rudas - Fuzzy Sets and Systems, 2011 - Elsevier
We enlarge the class of fuzzy transforms (F-transforms) by considering different types of
fuzzy partitions. New types of F-transforms are constructed based on B-splines, Shepard …

Multisignal 1-D compression by F-transform for wireless sensor networks applications

M Gaeta, V Loia, S Tomasiello - Applied Soft Computing, 2015 - Elsevier
In wireless sensor networks a large amount of data is collected for each node. The
challenge of transferring these data to a sink, because of energy constraints, requires …

Cubic B–spline fuzzy transforms for an efficient and secure compression in wireless sensor networks

M Gaeta, V Loia, S Tomasiello - Information Sciences, 2016 - Elsevier
Joining data compression and encryption is a way to keep secure data, as discussed by the
current literature. While data compression responds to the great demand on data storage …

Fuzzy transform and least-squares approximation: analogies, differences, and generalizations

G Patanè - Fuzzy sets and systems, 2011 - Elsevier
Investigating the relations between the least-squares approximation techniques and the
Fuzzy Transform, in this paper we show that the Discrete Fuzzy Transform is invariant with …

Data-driven fuzzy transform

G Patanè - IEEE Transactions on Fuzzy Systems, 2021 - ieeexplore.ieee.org
The Fuzzy transform is applied mainly to 1-D signals and 2-D data organized as a regular
grid (eg, 2-D images), thus, limiting its potential application to arbitrary data in terms of …
