The Transjugular Intrahepatic Portosystemic Shunt (TIPS) is an interventional treatment for cirrhotic patients with portal hyper-tension. In the light of our medical staa's experience, the consequences of TIPS are not homogeneous for all the patients and a subgroup dies in the rst six months after TIPS placement. An investigation for predicting the conduct(More)
Classifier combination falls in the so called data mining area. Its aim is to combine some paradigms from the supervised classification – sometimes with a previous non-supervised data division phase – in order to improve the individual accuracy of the component classifiers. Formation of classifier hierarchies is an alternative among the several methods of(More)
This paper describes the software framework that has been developed and that it is being used to build a control architecture for the navigation of a B21 mobile robot. The subsumption architecture and the multi-agent based controller architectures are analyzed and a software framework named SORGIN is presented as a structured programming tool that allows to(More)
This paper presents a new hybrid classifier that combines the probability based Bayesian Network paradigm with the Nearest Neighbor distance based algorithm. The Bayesian Network structure is obtained from the data by using the K2 structural learning algorithm. The Nearest Neighbor algorithm is used in combination with the Bayesian Network in the deduction(More)
In this paper we present an appearance-based method to be used for topologically localising the robot. The information extracted from the image sequences is just an approximation of the colour probability density function estimated using a non-parametric clustering paradigm, the Self-organising Map neural network, together with the information obtained from(More)
