Método de Inducción de Reglas de Clasificación Oblicuas Mediante un Algoritmo Evolutivo

Algoritmo de optimización mediante forrajeo de bacterias híbrido para el problema de selección de portafolios con restricción de cardinalidad

In this paper we tackle the optimal portfolio selection problem (PSP). Many research has been made around this subject mainly in two ways, whether extending the Markowitz model by taking into account real-world constraints (floor-ceiling, class and cardinality) or introducing different risk measures like semivariance, value at risk, absolute desviation, etc. Here, we present the preliminary res...

Identificación de Redes de Conocimiento mediante el Análisis de Redes Sociales

Knowledge networks facilitate knowledge transfer, particularly tacit knowledge. Identifying the knowledge network within an organization provides a means to better use the organizational resources and guide the efforts related to knowledge management. In this paper we describe a procedure to identify knowledge networks. This procedure is based on Social Network Analysis. Its application in one ...

Validación de un Sistema de Diálogo Mediante el uso de diferentes umbrales de poda en el proceso de reconocimiento automático de voz

This paper presents a new technique to validate the performance of dialogue systems focusing on two measures: response time a sentence understanding. Initially, the paper presents a description of the input interface of the dialogue system used in the experiments, including a classification of the recognition tasks considered. Later, it presents the basic features of the proposed technique and ...

Mejora de los sistemas multimodales mediante el uso de ganancia de información

This paper discusses the use of information gain (IG) to reduce and improve the textual information included in multi-modal information retrieval systems. Furthermore, a number of experiments are described that combine this reduction technique with a visualand textual-information merge. These show that the textual information manages to improve conventional multi-modal systems.
