This book was released on 2001 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: En esta Tesis Doctoral se investiga el rendimiento de algoritmos para Redes Neuronales Artificiales (RNAs) en el contexto de aplicaciones relacionadas con la predicción de series temporales complicadas. Se postula un modelo basado en RBFs (Radial Basis Functions, Redes de Funciones Radiales) y en la descomposición ortogonal de matrices de datos formadas a partir de valores endógenos de series temporales,y se demuestra la capacidad del mismo para conseguir predicicones más precisas, con lo cual se puede ayudar a la mejora de acciones de control o de toma de decisiones en entornos industriales, sociales y económicos. El modelo descrito se denota por "NAPA-PRED" (Neural model with Automatic Parameer Adjustement for PREDiction; o Modelo Neuronal con Ajuste Automático de Parámetros para Predicción). Este modelo es capaz de determinar el número óptimo, así como la configuración o disposición temporal, de los retardos en los nodos de entrada.También es capaz de determinar el núemro óptimo (a efectos prácticos) de nodos o neuronas (RBFs) en la red neuronal artificial. También, se consigue una mejora adicional mediante la hibridación de este modelo con otras técnicas como el Análisis de Componentes Principales (PCA) para controlar el efecto de datos exógenos (externos a la serie), o la metodología estadística ARIMA para modelar y reducir el error de aproximación neuronal. Adicionalmente, se describe una nueva forma de paralelizar el esquema de descomposición matricial empleado, en lo que concierne a la transformación QR-cp, lo cual conduce a una ganancia de velocidad muy aceptable cuando se implementa el procedimiento sobre plataformas de cómputo relativamente asequible, como "clusters" de computadores personales. Las aplicaciones que se describen en las seccioens experimentales incluyen la predicicóna largo plazo de series temporales de comportamiento caótico, la mejora en la predicción del consumo en una red de distribución de aguas, o la predicción bursátil con datos de algunas compañías bancarias españolas.
Book Synopsis ANÁLISIS DE SERIES TEMPORALES MEDIANTE REDES NEURONALES. EJEMPLOS CON MATLAB by : CESAR PEREZ LOPEZ
Download or read book ANÁLISIS DE SERIES TEMPORALES MEDIANTE REDES NEURONALES. EJEMPLOS CON MATLAB written by CESAR PEREZ LOPEZ and published by CESAR PEREZ. This book was released on with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: MATLAB cuenta con la herramienta Deep Learning Toolbox que proporciona algoritmos, funciones y aplicaciones para crear, entrenar, visualizar y simular redes neuronales. Puede realizar clasificación, regresión, agrupamiento, reducción de dimensionalidad, pronóstico de series temporales y modelado y control de sistemas dinámicos. Las redes neuronales dinámicas son adecuadas para la predicción de series temporales. Puede utilizar la app Neural Net Time Series para resolver diferentes tipos de problemas de series temporales. Generalmente es mejor comenzar con la GUI y luego usarla para generar automáticamente scripts de línea de comandos. Antes de utilizar cualquiera de los métodos, el primer paso es definir el problema seleccionando un conjunto de datos. Cada GUI tiene acceso a muchos conjuntos de datos de muestra que puede utilizar para experimentar con la caja de herramientas. Si tiene un problema específico que desea resolver, puede cargar sus propios datos en el espacio de trabajo. Con MATLAB es posible resolver tres tipos diferentes de problemas de series temporales. En el primer tipo de problema de series de tiempo, se busca predecir valores futuros de una serie de tiempo y(t) a partir de valores pasados de esa serie de tiempo y valores pasados de una segunda serie de tiempo x(t). Esta forma de predicción se denomina red autorregresiva no lineal con entrada exógena (externa), o NARX. En el segundo tipo de problema de series temporales, sólo hay una serie involucrada. Los valores futuros de una serie temporal y(t) se predicen sólo a partir de valores pasados de esa serie. Esta forma de predicción se llama autorregresiva no lineal o NAR. El tercer problema de series de tiempo es similar al primer tipo, en el sentido de que están involucradas dos series, una serie de entrada (predictores) x(t) y una serie de salida (respuestas) y(t). Este libro desarrolla los métodos de predicción con series temporales a través de redes neuronales con MATLAB.

The contributions cover both theoretical developments and practical applications in the various areas of Soft Computing.
Book Synopsis Lectures on Soft Computing and Fuzzy Logic by : Antonio Di Nola
Download or read book Lectures on Soft Computing and Fuzzy Logic written by Antonio Di Nola and published by Springer Science & Business Media. This book was released on 2001-07-31 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume collects selected papers arising from lectures delivered by the authors at the School on Fuzzy Logic and Soft Computing held during the years 1996/97/98/99 and sponsored by the Salerno University. The authors contributing to this volume agreed with editors to write down, to enlarge and, in many cases, to rethink their original lectures, in order to offer to readership, a more compact presentation of the proposed topics. The aim of the volume is to offer a picture, as a job in progress, of the effort that is coming in founding and developing soft computing's techniques. The volume contains papers aimed to report on recent results containing genuinely logical aspects of fuzzy logic. The topics treated in this area cover algebraic aspects of Lukasiewicz Logic, Fuzzy Logic as the logic of continuous t-norms, Intuitionistic Fuzzy Logic. Aspects of fuzzy logic based on similar ity relation are presented in connection with the problem of flexible querying in deductive database. Departing from fuzzy logic, some papers present re sults in Probability Logic treating computational aspects, results based on indishernability relation and a non commutative version of generalized effect algebras. Several strict applications of soft computing are presented in the book. Indeed we find applications ranging among pattern recognition, image and signal processing, evolutionary agents, fuzzy cellular networks, classi fication in fuzzy environments. The volume is then intended to serve as a reference work for foundational logico-algebraic aspect of Soft Computing and for concrete applications of soft computing technologies.

This book was released on 2000-06-05 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains articles accepted for presentation during The Intelligent Information Systems Symposium I1S'2000 which was held in Bystra, Poland, on June 12-16, 2000. This is ninth, in the order, symposium organized by the Institute of Computer Science of Polish Academy of Sciences and devoted to new trends in (broadly understood) Artificial Intelligence. The idea of organizing such meetings dates back to 1992. Our main in tention guided the first, rather small-audience, workshop in the series was to resume the results gained in Polish scientific centers as well as contrast them with the research performed by Polish scientists working at the uni versities in Europe and USA. This idea proved to be attractive enough that we decided to continue such meetings. As the years went by, the workshops has transformed into regular symposia devoted to such fields like Machine Learning, Knowledge Discovery, Natural Language Processing, Knowledge Based Systems and Reasoning, and Soft Computing (Le. Fuzzy and Rough Sets, Bayesian Networks, Neural Networks and Evolutionary Algorithms). At present, about 50 papers prepared by researches from Poland and other countries are usually presented. Besides, for several years now, the symposia are accompanied by a number of tutorials, given by the outstanding scientists in their domain. Up to this year the proceedings were published as our local publication and they were distributed among the scientific libraries. We feel however, that the subject matter as well as the quality of papers is sufficient to present the proceedings to a broader scientific audience.

This is eleventh, in the order, symposium organized by the Institute of Computer Science of Polish Academy of Sciences and devoted to new trends in (broadly understood) ArtificialIntelligence. The meetings started back to 1992. With small initial audience, workshops in the series grew to an important meeting of Polish and foreign scientists working at the universities in Europe, Asia and the Northern America. Over years, the workshops transformed into regular symposia devoted to latest trends in such fields like Machine Learning, Knowledge Discovery, Natural Language Processing, Knowledge Based Systems and Reasoning, and Soft Computing (i.e. Fuzzy and Rough Sets, Bayesian Networks, Neural Networks and Evolutionary Algorithms). At present, about 50-60 papers are accepted each year. Besides, for several years now, the symposia are accompanied by a number of tutorials, given by the outstanding scientists in their domain. The main topics of this year symposium included: • decision trees and other classifier systems • neural network and biologiccally motivated systems • clustering methods • handling imprecision and uncertainty • deductive, distributed and agent-based systems We were pleased to see the continuation of the last year trend towards an increase in the number of co-operative contributions and in the number and diversity of practical applications of theoretical research.
