چکیده
Mountain forests are exposed to extreme conditions (e.g., strong winds and intense solar radiation) various types of damage by insects such as bark beetles, which makes them very sensitive climatic changes. Therefore, continuous monitoring is crucial, remote-sensing techniques allow the transboundary areas where a common policy needed protect monitor environment. In this study, we used Sentinel-2 Landsat 8 open data assess forest stands classification UNESCO Krkonoše/Karkonosze Transboundary Biosphere Reserve, undergoing dynamic changes in recovering woodland vegetation due an ecological disaster that led death large portion forests. Currently, protected area, dry big trunks branches coexist with naturally occurring young This heterogeneity generates mixes, hinders automation classification. Thus, three machine learning algorithms—Random Forest (RF), Support Vector Machine (SVM), Artificial Neural Network (ANN)—to classify dominant tree species (birch, beech, larch spruce). The best results were obtained for SVM RBF classifier, offered average median F1-score oscillated around 67.2–91.5% depending on species. maps, based multispectral satellite images, also compared classifications made same area basis hyperspectral APEX imagery (288 spectral bands three-meter resolution), indicating high convergence recognition woody

متن کاملNovel solutions for an old disease: diagnosis of acute appendicitis with random forest, support vector machines, and artificial neural networks.
BACKGROUND Diagnosing acute appendicitis clinically is still difficult. We developed random forests, support vector machines, and artificial neural network models to diagnose acute appendicitis. METHODS Between January 2006 and December 2008, patients who had a consultation session with surgeons for suspected acute appendicitis were enrolled. Seventy-five percent of the data set was used to c...

Application of Artificial Neural Networks and Support Vector Machines for carbonate pores size estimation from 3D seismic data
This paper proposes a method for the prediction of pore size values in hydrocarbon reservoirs using 3D seismic data. To this end, an actual carbonate oil field in the south-western part ofIranwas selected. Taking real geological conditions into account, different models of reservoir were constructed for a range of viable pore size values. Seismic surveying was performed next on these models. F...

Background: Multiple sclerosis (MS) is a degenerative inflammatory disease which is most commonly diagnosed by magnetic resonance imaging (MRI). But, since the MRI device uses of a magnetic field, if there are metal objects in the patient's body, it can disrupt the health of the patient, the functioning of the MRI, and distortion in the images. Due to limitations of using MRI device, screening ...
