Red neuronal convolucional rápida sin fotogramas para reconocimientos de dígitos
(Unión Científica Internacional de Radio, 2011)
In this paper a bio-inspired six-layer convolutional network (ConvNet) non-frame based for digit recognition is shown. The system has been trained with the backpropagation algorithm using 32x32 images from the MNIST ...

Sistema de reconocimiento de caracteres de alta velocidad basado en eventos
(2011)
Spike-based processing technology is capable of very high speed throughput, as it does not rely on sensing and processing sequences of frames. Besides, it allows building complex and hierarchically structured cortical-like ...

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 ...

On spike-timing-dependent-plasticity, memristive devices, and building a self-learning visual cortex
(Frontiers Media, 2011)
In this paper we present a very exciting overlap between emergent nanotechnology and neuroscience, which has been discovered by neuromorphic engineers. Specifically, we are linking one type of memristor nanotechnology ...

Generalized Alpha-Beta Divergences and Their Application to Robust Nonnegative Matrix Factorization
(Multidisciplinary Digital Publishing Institute, 2011)
We propose a class of multiplicative algorithms for Nonnegative Matrix Factorization (NMF) which are robust with respect to noise and outliers. To achieve this, we formulate a new family generalized divergences referred ...

Experimental study of two-tone intermodulation products in a communications modulator
(Wiley, 2011-01)
This article presents the experimental nonlinear characterization of a quadrature modulator following a two‐tone test approach. The observed intermodulation products show different slopes with respect to the desired carrier ...
