El test Finger-to-nose test (FNT) es una evaluación neurológica para estudiar la coordinación. Se presenta una metodología de análisis de datos de FNT, que permite evaluar la evolución del estado de enfermos de Ataxia ...

Esta tesis presenta un estudio de las redes neuronales de Hopfield, en cuanto a su capacidad para resolver problemas de optimización. El análisis teórico de las características de estos sistemas se abordan con rigor ...

We propose the higher order extension of numerical methods that preserve the energy-diminishing feature of a system with Lyapunov function.

This paper proposes an adaptative control algorithm, which is designed by adding a parametric identification method to a non-linear controller. The identification module is built upon the Hopfield neural network, resulting in ...

Esta tesis estudia métodos de integración numérica geométrica, específicamente, métodos numéricos diseñados para conservar la función de Lyapunov de un sistema dinámico. En otras palabras, se proponen aproximaciones numéricas ...

A non-negative matrix factorization approach to dimensionality reduction is proposed to aid classification of images. The original images can be stored as lower-dimensional columns of a matrix that hold degrees of belonging ...

In this contribution we implement and assess numerical methods for gradient systems, i.e. dynamical systems that possess a Lyapunov function, and consequently are stable. In particular, we claim that discrete gradient ...

This paper proposes a method for clustering of time series, based upon the ability of deep Reservoir Computing networks to grasp the dynamical structure of the series that is presented as input. A standard clustering ...
