RESUMENLos algoritmos multiclasificadores se han mostrado particularmente eficientes para trabajar sobre espacios de datos grandes y complejos como los llamados flujos de datos. En estos flujos, durante la clasificación, aparecen conceptos que cambian con el tiempo, por lo que los métodos para su minería, sobre todo los que detectan y se adaptan a estos cambios, son importantes por su aplicación en áreas como: bioinformática, medicina, economía y finanzas, industria, medio ambiente, entre otras.
ENSEMBLE ALGORITHM FOR DATA STREAMS WITH CONCEPT DRIFT ABSTRACTThe ensemble algorithms have been particularly efficient to work on areas of large and complex data as so-called data streams. In these flows, during qualifying, they appear concepts change over time, so that its mining methods, especially those that detect and adapt to these changes are important for their application in areas such as bioinformatics, medicine, economics and finance, industry, environment, among others. This research proposes a new ensemble algorithm that adapts to concepts drift, have weighted voting with a new way to adjust the weights and can vary the type of basic classifier. The algorithm was implemented in support and under the demands of the work environment MOA (Massive Online Analysis) facilitating comparison with other known algorithms and the generation of synthetic data bases that simulate changes in concepts. For experimentation, experiences they were generated under known, such as artificial concepts: SEA, LED, STAGGER and hyperplane; managing to show high resilience and stability of the algorithm against different simulated situations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
