Prototype selection is one of the most common preprocessing tasks in data mining applications. The vast amounts of data that we must handle in practical problems render the removal of noisy, redundant or useless instances a convenient first step for any real-world application. Many algorithms have been proposed for prototype selection. For difficult problems, however, the use of only a single method would unlikely achieve the desired performance. Similar to the problem of classification, ensembles of prototype selectors have been proposed to overcome the limitations of single algorithms. In ensembles of prototype selectors, the usual combination method is based on a voting scheme coupled with an acceptance threshold. However, this method is suboptimal, because the relationships among the prototypes are not taken into account. In this paper, we propose a different approach, in which we consider not only the number of times every prototype has been selected but also the subsets of prototypes that are selected. With this additional information we develop GEEBIES, which is a new way of combining the results of ensembles of prototype selectors. In a large set of problems, we show that our proposal outperforms the standard boosting approach. A way of scaling up our method to large datasets is also proposed and experimentally tested.

A ubiquitous target SNARE protein that interacts with SYNTAXIN and SYNAPTOBREVIN. It is a core component of the machinery for intracellular MEMBRANE FUSION. The sequence contains 2 SNARE domains, one is the prototype for the Qb-SNARES, and the other is the prototype for the Qc-SNARES.
Planning that has the goals of improving health, improving accessibility to health services, and promoting efficiency in the provision of services and resources on a comprehensive basis for a whole community. (From Facts on File Dictionary of Health Care Management, 1988, p299)
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
