Networking: media, representation and architecture
(Proceedings of the 5th Conference of Design and Decision Support Systems in Architecture and Urban Planning, 2000-01)In this paper we present a pedagogic work, carried out in a third year architecture course, focused on the relationship between teaching content and media. The subject-matter of the course is the concept ... -
Validation of an acoustical modelling of emotional expression in Spanish using speech synthesis techniques
(2000-09)This paper describes the methodology used for validating the results obtained in a study about acoustical modelling of emotional expression in Castilian Spanish. We have obtained a set of rules that ... -
Iniciativas para motivar a los alumnos de Programación
(2000-09)La asignatura de Programación constituye una base fundamental para las diversas carreras de ingeniería. Los posibles enfoques que se pueden utilizar, tanto de contenidos como de método docente, son muy ... -
A BiCMOS discriminator interface for the SPD
(2000-09)A prototype chip for the analogue readout of the SPD in the LHCb Calorimeter is presented. The chip has been designed using the 0.8mm-BiCMOS technology of AMS and optimised for minimum size and ... -
Genetic Classifier System as a heuristic weighting method for a Case-Based Classifier System
(2000-10)This paper proposes how to use a Genetic Classifier System as a heuristic weighting method for a Case-Based Classifier System. The preliminary results are performed into a specific domain: the prediction ... -
MultiObjective Learning in a Genetic Classifier System (MOLeCS)
(2000-10)MOLeCS is a new Classifier System which addresses its learning as a multiobjective optimization of two goals: classifier accuracy and generality. These objectives are both emphasized in the fitness ... -
BASTIAN: incorporating the Rough Sets theory into a Case-Bases Classifier System
(2000-10)This paper proposes how to incorporate the Rough Sets theory as a weighting method into a Case-Based Classifier System. This hybrid system has been implemented into the platform called BASTIAN ( ... -
¿Cómo predecir la evolución del alumno?
(Actas de las VII Jornadas de Enseñanza universitaria de la Informática, 2001-07)Un aspecto muy importante en la enseñanza acualquier nivel es poder predecir a tiempo si unalumno conseguirá superar una asignatura. De estamanera, si se detecta a tiempo una desviación enel aprendizaje ... -
Mobile robot guidance using cellular neural networks and fuzzy logic
(2001-10)We show how a Cellular Neural Networks based image processing system together with a Tuzzy Logic controller are capable of providing the necessary signal processing to guide an autonomous mobile robot ... -
Extracting relevant information from input-output data
(4rt Congrés Català d'Intel.ligència Artificial, Barcelona, 24-25 d'octubre de 2001, 2001-10)In this paper a set of heuristic criteria devised to address the problems encountered in designing a fuzzy system from input-output data is presented. In particular, we show how to discriminate ... -
Component Analysis and Time Series Prediction
(2001-10)The relation between component analysis (PCA and ICA) and Multi-resolution Filtering is explained and its use to improve the prediction error in a time series is shown. An example applying the previous ... -
Classifying Microcalcifications in Digital Mammograms using Machine Learning techniques
(2001-10)This paper presents a Computer Aided Diagnosis (CAD) of breast cancer from mammograms. The first part involves severa! image processing techniques, which extract a set of features from the microcalcifications ... -
