Development and evaluation of perceptually adapted colour gradients
(Institution of Engineering and Technology (IET), 2013)
In this study a set of colour gradients based on colour visual perception, which use International Commission on Illumination (CIE) L*a*b* colour space, is presented. The main objective is the study of how the colour ...

Clustering learning for robotic vision
(2013)
We present the clustering learning technique applied to multi-layer feedforward deep neural networks. We show that this unsupervised learning technique can compute network filters with only a few minutes and a much reduced ...

Solving permutations in frequencyy-domain for blind separation of an arbitrary number of speech sources
(Acoustical Society of America, 2011)
Blind separation of speech sources in reverberant environ ments is usually performed in the time-frequency domain, which gives rise to the permutation problem: the different ordering of estimated sources for different ...

Upgrading Behavioral Models for the Design of Digital Predistorters
(MDPI AG, 2021)
This work presents a strategy to upgrade models for power amplifier (PA) behavioral modeling and digital predistortion (DPD). These incomplete structures are the consequence of nonlinear order and memory depth model ...

Unsupervised and Computationally Lightweight Spectrum Sensing in IoT Devices †
(MDPI, 2022)
Principal component analysis (PCA) is a widespread technique in data analysis. Recently, the L1-norm has been proposed as an alternative criterion to classical L2-norm in PCA due to its greater robustness to outliers. The ...
