The Self Organizing Map (SOM) published by Teuvo Koho-nen in 1982 is a neural unsupervised model capable of organizing data on a topographic neural surface. Furthermore, this model shows the remarkable ability to preserve topological connections during the interaction between two neuronal layers (for example, the retina and the surface of a model c...

A fundamental problem in semantic cognition is the representation of human concepts in the brain. Much of the knowledge acquired in the last decades comes from the study of dissociations found in patients with acquired difficulties in language, perception, and action. In particular, some deficits involve loss of knowledge about tools. The dissociat...

This article introduces a dataset containing electricity consumption records of residential households in Uruguay (mostly in Montevideo). The dataset is conceived to analyze customer behavior and detect patterns of energy consumption that can help to improve the service. The dataset is conformed by three subsets that cover total household consumpti...

Breaking down the aggregated energy consumption into a detailed consumption per appliance is a crucial tool for energy efficiency in residential buildings. Non-intrusive load monitoring allows implementing this strategy using just a smart energy meter without installing extra hardware. The obtained information is critical to provide an accurate cha...

Non-intrusive load monitoring allows breaking down the aggregated household consumption into a detailed consumption per appliance, without installing extra hardware, apart of a smart meter. Breakdown information is very useful for both users and electric companies, to provide an accurate characterization of energy consumption, avoid peaks, and elab...

This thesis deals with some cognition pathologies, seen from the mathematical tools' point of view. The considered pathologies are related to the semantic memory of the patients, and the associated problems are in general centered around some form of degradation of this critical cognitive function. One of the rare tools available for the diagnostic...

A naive exhaustive manual inspection of port-of-entry is the most secure inspection policy. However, the number of within containers allows only to check a limited number of containers each day. The aim of this paper is to offer an automatic, simple and intuitive algorithm to select which containers should be inspected, following a given training s...

A natural way to avoid the injection of potentially dangerousor illicit products in a certain country is by means of protection, following a strict port-of-entry inspection policy. A naive exhaustive manual inspection is the most secure policy. However, the number of within containers allows only to check a limited number of containers by day. As a...

1 Introducción y agradecimientos Este trabajo consiste en la exposición informal de algunos aspectos formales de dos modelos neurales: el viejo perceptrón de Rosenblatt, de fines de los cincuenta y la Red Neural Aleatoria de Gelenbe, de fines de los ochenta. Entre ambos mediaron dos libros: el de Perceptrones de Minsky y Pappert, de fines de los se...

A total of 286 wheat samples for human consumption collected during 1997-2003 from four wheat-producing localities of south-western Uruguay were screened for deoxynivalenol (DON). Quantification was carried on by an immunochemical method using immunoaffinity columns and fluorimetric detection. The incidence of DON was high during the whole survey (...

A χ -type goodness of fit test for a location and scale family is presented. The test uses the Transformed Empirical Processes introduced by A. Cabaña and E.M. Cabaña and is based in a particular expansion on the L space of the null hypothesis standard distribution. It is implemented in a particular contiguous case, and compared with a classical χ...
