Uso de Algoritmos Genéticos na Seleção de Atributos para Classificação de Regiões

The technological advances about remote sensing allows a better identification of urban targets in the images. The aim of this work is to classify automatically the urban spaces applying feature extraction and selection techniques, in high resolution images. To classify the road network and others urban components, some shape features that permit to recognize different objects with analogous sp...

Seleção de Atributos Utilizando Algoritmos Genéticos para Detecção do Vandalismo na Wikipedia

This paper presents a genetic algorithm based approach for reducing the set of attributes for detecting vandalism in Wikipedia. Our experimental results show that the proposed approach is able to reduce the set of attribute in 83% with no significant impact in detection effectiveness. Moreover, our approach is able to select a number of attributes that leads to better results if compared to a s...

Aspectos Genéticos do Hipotireoidismo Congênito

Genetic Aspects in Congenital Hypothyrodism. Congenital hypothyroidism (CH) affects between 1:3,000 and 1:4,000 newborns. Many genes are essential for normal development of the hypothalamus-pituitary-thyroid axis and hormone production, and are associated with CH. About 85% of primary hypothyroidism is called thyroid digenesis and evidence suggests that mutations in transcription factors (TTF2,...

Optimización de Control Difuso Aplicando Algoritmos Genéticos

Algoritmos Genéticos para Consultas por Similaridade Aproximadas

The similarity search process on complex domains for exact answer is an expensive process. However, the multimedia data comparison operations usually consider some extracted features from the elements, instead of the elements themselves. Therefore, trading exact answering with query time response can be a worth exchange. In this work we developed two techniques based on genetic algorithms to al...
