Boosting offline handwritten text recognition in historical documents with few labeled lines
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper we address the problem of offline handwritten text recognition (HTR) in historical documents when few labeled samples are available and some of them contain errors in the train set. Our three main contributions ...

Turbo EP-Based Equalization: A Filter-Type Implementation
(IEEE Communications Society, 2018-09)
We propose a novel filter-type equalizer to improve the solution of the linear minimum-mean squared-error (LMMSE) turbo equalizer, with computational complexity constrained to be quadratic in the filter length. When ...

On the implementation of distributed asynchronous non-linear kernel methods over wireless sensor networks
(Springer, 2015)
In this paper, we face the implementation of a non-linear kernel method for regression on a wireless sensor network (WSN) based on MICAz motes. The operating system used is TinyOS 2.1.1. The algorithm estimates the value ...

Crossing points detection in plain weave for old paintings with deep learning
(Elsevier, 2023-11)
In the forensic studies of painting masterpieces, the analysis of the support is of major importance. For plain weave fabrics, the densities of vertical and horizontal threads are used as main features, while angle ...

A Low-Complexity Double EP-based Detector for Iterative Detection and Decoding in MIMO
(Institute of Electrical and Electronics Engineers Inc., 2021)
We propose a new iterative detection and decoding (IDD) algorithm for multiple-input multiple-output (MIMO) based on expectation propagation (EP) with application to massive MIMO scenarios. Two main results are ...

Machine Learning for handwriting text recognition in historical documents
(2021-12-17)
Olmos ABSTRACT In this thesis, we focus on the handwriting text recognition task over historical documents that are difficult to read for any person that is not an expert in ancient languages and writing style. We aim ...
Tesis Doctoral
Expectation propagation as a solution for digital communication systems.
(2018-11-16)
In the context of digital communications, a digital receiver is required to provide an estimation of the transmitted symbols. Nowadays channel decoders highly benefit from soft (probabilistic) estimates for each transmitted ...
