Procesamiento paralelo y distribuido aplicado al almacenamiento y recuperación de información documental

Abstract

Para la consecución del objetivo propuesto, se ha trabajado con redes neuronales con función de base radial, perceptrones multicapa y con métodos constructivos como Cascade Correlation. Los resultados obtenidos con estas arquitecturas no han sido positivos, pues, o bien fracasaban en el ajuste, o bien, la memoria requerida era muy superior a su alternativa con Índices Inversos. Por este motivo, se ha propuesto una nueva arquitectura, la de red Hiperbandas, cuyas características más relevantes se pueden resumir en que se trata de una red que se construye ex profeso para clasificar un conjunto de datos de entrada sin interacción del usuario, con error cero y adecuada para situaciones donde los patrones de entrada se agrupan formando clases que pueden estar solapadas. Para verificar las prestaciones de esta nueva arquitectura, se han realizado comparaciones con el sistema usual basado en la técnica de Índices Inversos implementado mediante un B-Tree simple. Para llevar a cabo este análisis, se han examinado los parámetros que se utilizan generalmente para evaluar el rendimiento de un DRS, estos son: el tiempo de indexación, el espacio de almacenamiento requerido, la eficiencia de búsqueda y la efectividad de la consulta.
