Fuzzy transforms method in prediction data analysis

F Di Martino, V Loia, S Sessa - Fuzzy Sets and Systems, 2011 - Elsevier
We present a prediction method based on Fuzzy transforms for forecasting problems and we
compare it with the well known Wang–Mendel's one. Another comparison is made on the …

Fuzzy transform based compression of electric signal waveforms for smart grids

V Loia, S Tomasiello, A Vaccaro - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
In this paper, a fuzzy-based paradigm for data compression aimed at reducing the
computational burden of data analysis in smart grids (SGs) is proposed. In the SG context, it …

A segmentation method for images compressed by fuzzy transforms

F Di Martino, V Loia, S Sessa - Fuzzy sets and systems, 2010 - Elsevier
In this paper we describe a segmentation method applied to images which are compressed
by using Fuzzy Transforms. The segmentation of the images is realized via the FGFCM (Fast …

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 …

Fuzzy transforms method and attribute dependency in data analysis

F Di Martino, V Loia, S Sessa - Information Sciences, 2010 - Elsevier
In this paper, we present a method based on fuzzy transforms to establish dependencies
between numerical attributes in datasets. We find the best fuzzy partitions of the attribute …

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 …

Compression and decompression of images with discrete fuzzy transforms

F Di Martino, S Sessa - Information Sciences, 2007 - Elsevier
In foregoing papers we have used the compression/decompression method of images
based on the concept of discrete fuzzy transform (and its inverse) of a function f defined on a …

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 transforms for compression and decompression of color videos

F Di Martino, V Loia, S Sessa - Information Sciences, 2010 - Elsevier
We use fuzzy transforms for coding/decoding color frames of videos and we compare the
results with the same frames reconstructed with the standard JPEG method. We classify all …

Necessary and sufficient conditions for generalized uniform fuzzy partitions

M Holčapek, I Perfilieva, V Novák, V Kreinovich - Fuzzy Sets and Systems, 2015 - Elsevier
The fundamental concept in the theory of fuzzy transform (F-transform) is the fuzzy partition,
which is a generalization of the classical concept of partition. The original definition assumes …
