ABSTRACT Mapping and assessment of mangrove environment are crucial since the mangrove has an important role in the process of human-environment interaction. In Indonesia alone, 25% of South East Asia's mangroves available are under threat. Recognizing the availability and the ability of new sensor of Landsat data, this study investigates the use of Landsat ETM + 7 and Landsat 8, acquired in 2002 and 2013 respectively, for assessing the extent of mangrov...

Department of Information Technology, FATEC-SP/CEETEPS, S?o Paulo, Brazil . ABSTRACT Concept learning is a kind of classification task that has interesting practical applications in several areas. In this paper, a new evolutionary concept learning algorithm is proposed and a corresponding learning system, called ECL ( Evolutionary Concept Learner ), is implemented. This system is compared to three traditional learning systems: MLP ( Multilayer Perceptron ), ID3 ( Iterative Dichotomiser ) and NB ( Naïve Bayes ). The comparison takes into account target concepts of varying complexities (e.g., with interacting attributes) and different qualities of training sets (e.g., with imbalanced classes and noisy class labe...
