Effectiveness of local feature selection in ensemble learning for prediction of antimicrobial resistance
2008
In the real world concepts are often not stable but change over time. A typical example of this in the biomedical context is antibiotic resistance, where pathogen sensitivity may change over time as pathogen strains develop resistance to antibiotics that were previously effective. This problem, known as concept drift (CD), complicates the task of learning a robust model. Different ensemble learning (EL) approaches (that instead of learning a single classifier try to learn and maintain a set of classifiers over time) have been shown to perform reasonably well in the presence of concept drift. In this paper we study how much local feature selection (FS) can improve ensemble performance for da…
Dimensiones y espacios electorales en las elecciones autonómicas vascas de 2012 y 2016
2018
En este artículo se analiza la incidencia de los principales cleavages –ideológico e identitario- presentes en la competición electoral vasca para las elecciones de 2012 y 2016, e intenta constituirse como una vía intermedia entre aquellos desarrollos teóricos que señalan la preeminencia de alguna de estas dimensiones de forma generalizada para todas las formaciones. Para ello abordamos los comicios a través de la teoría espacial del voto, mediante la utilización de modelos de regresión logística binaria. Esto nos ha permitido conocer el desigual peso otorgado por cada uno de los electorados de las diferentes formaciones políticos a estas fracturas centrales. Asimismo, para las elecciones d…
Theoretical and Analytical Framework
2021
Analytically, the present work relies on two foundations, Anthony Downs’ (1957) Proximity model of electoral competition which states that political parties or candidates will seek to position themselves as close as possible to the (preferred) policy positions of voters and Ian Budge’s past election model (1994), according to which parties and candidates use the results of past elections in order to gain information about the electorate landscape. Both models rely on a ‘marketplace’ analogy with demand and supply. Candidates, parties, and politicians supply policies (advertised as policy positions), while the electorate, voters, and constituencies demand policies. Just like in a marketplace…
A Similarity Evaluation Technique for Cooperative Problem Solving with a Group of Agents
1999
Evaluation of distance or similarity is very important in cooperative problem solving with a group of agents. Distance between problems is used by agents to recognize nearest solved problems for a new problem, distance between solutions is necessary to compare and evaluate the solutions made by different agents, and distance between agents is useful to evaluate weights of the agents to be able to integrate them by weighted voting. The goal of this paper is to develop a similarity evaluation technique to be used for cooperative problem solving with a group of agents. Virtual training environment used for this goal is represented by predicates that define relationships within three sets: prob…
<title>Dynamic integration of multiple data mining techniques in a knowledge discovery management system</title>
1999
One of the most important directions in improvement of data mining and knowledge discovery, is the integration of multiple classification techniques of an ensemble of classifiers. An integration technique should be able to estimate and select the most appropriate component classifiers from the ensemble. We present two variations of an advanced dynamic integration technique with two distance metrics. The technique is one variation of the stacked generalization method, with an assumption that each of the component classifiers is the best one, inside a certain sub area of the entire domain area. Our technique includes two phases: the learning phase and the application phase. During the learnin…
Handling local concept drift with dynamic integration of classifiers : domain of antibiotic resistance in nosocomial infections
2006
In the real world concepts and data distributions are often not stable but change with time. This problem, known as concept drift, complicates the task of learning a model from data and requires special approaches, different from commonly used techniques, which treat arriving instances as equally important contributors to the target concept. Among the most popular and effective approaches to handle concept drift is ensemble learning, where a set of models built over different time periods is maintained and the best model is selected or the predictions of models are combined. In this paper we consider the use of an ensemble integration technique that helps to better handle concept drift at t…
Elections ordinaires et aménagements constitutionnels
2001
It is widely held that voting in the course of ordinary elections has no significant influence on the constitutional regime or order of a country. At least three powerful arguments are provided in support of that view. First, to claim that, at the same time as they play, players can change the rules is, to say the least, logically puzzling. A second argument refers to the motivations and possibilities of voters : voters, this argument says, are not really interested in constitutional issues and, even if they were, are particularly ill-equiped to understand their implications. The third argument rests on the observation of what obtains in practice : as a matter of fact, constitutional issues…
Voting Transitions in the 2019 Valencian Autonomous Community’s Elections
2020
The political fragmentation following the 2008 Financial Crisis and its economic, social, political and institutional fall-out have led to a growing left-right polarisation of politics and a weakening of the middle ground. The effective number of parliamentary parties is at an all-time high both inthe Spanish Parliament (Congreso) and in the Valencian Autonomous Parliament (Corts). Voters are spoilt for choice and switch party more often. This paper uses transfer matrices to analyse the shifting voting patterns in the European, General, Regional, and Local elections held during 2019 in The Valencian Country. The most salient result is the ever-shifting pattern at each end of the political s…
The 2019 Local Elections in Valencia’s Metropolitan Area
2020
Voting behaviour in Valencia’s Metropolitan Area can be split into four periods: (1) During the early years of democracy (1979-1991) following the Franco dictatorship, the area was a stronghold of the Left; (2) In 1991, the City of Valencia switched and was governed by the Right; (3) In 2011, the Right extended its control to the whole of the Metropolitan Area; (4) In the May 2015 elections, the Left won not only in the ‘red’ metropolitan belt but also in the City of Valencia. This study looks at what happened in the last set of local elections in 2019. To this end, we begin with a brief review of the election results, voting trends, and the institutional performance of each party since the…
