“… [40] extended this system with assigning weights to the detector algorithms according to their individual accuracies. Hajdu et al [41] made a further extension by introducing corresponding diversity measures to discover the dependencies of the detector algorithms better. A detailed comparison of the aforementioned algorithms is enclosed in Table 1 (see Appendix).…”

In this paper, we give a review on automatic image processing tools to recognize diseases causing specific distortions in the human retina. After a brief summary of the biology of the retina, we give an overview of the types of lesions that may appear as biomarkers of both eye and non-eye diseases. We present several state-of-the-art procedures to extract the anatomic components and lesions in color fundus photographs and decision support methods to help clinical diagnosis. We list publicly available databases and appropriate measurement techniques to compare quantitatively the performance of these approaches. Furthermore, we discuss on how the performance of image processing-based systems can be improved by fusing the output of individual detector algorithms. Retinal image analysis using mobile phones is also addressed as an expected future trend in this field.

“…Ennek eredményeként a vizsgált területről 47 késő neolitikus településről sikerült adatbázist összeállítania. 36 Polgár-Csőszhalom és maga a Polgár-sziget regionális és szupraregionális léptékű kapcsolatait a helyi kőeszközök nyersanyag forrásainak statisztikai elemzése alapján Faragó Norbert, Janusz Kozlowski és Malgorzata Kaczanowska körvonalazta. 37 Hasonlóan fontos eredménnyel jártak a csőszhalmi korai réztárgyak nyersanyagának 5 izotópos vizsgálatai, amelyek egy határozott balkáni kapcsolatrendszert és beszerzési hálózatot bizonyítottak.…”

A felső-Tisza-vidéki Polgár-szigeten a késő neolitikumban kialakult településhálózatot vizsgáljuk a jelen tanulmány keretein belül. Ehhez kapcsolódóan Polgár-Csőszhalom környezetében végzett, több évig tartó geomágneses munkák eredményét mutatjuk be. Ez alapján a Csőszhalom és a körülötte található horizontális település együttesen 67,5 hektár nagyságúnak határozható meg.

A stochastic approach to handle resource constraints as knapsack problems in ensemble pruning

Ensemble-based methods are highly popular approaches that increase the accuracy of a decision by aggregating the opinions of individual voters. The common point is to maximize accuracy; however, a natural limitation occurs if incremental costs are also assigned to the individual voters. Consequently, we investigate creating ensembles under an additional constraint on the total cost of the members. This task can be formulated as a knapsack problem, where the energy is the ensemble accuracy formed by some aggregation rules. However, the generally applied aggregation rules lead to a nonseparable energy function, which takes the common solution tools—such as dynamic programming—out of action. We introduce a novel stochastic approach that considers the energy as the joint probability function of the member accuracies. This type of knowledge can be efficiently incorporated in a stochastic search process as a stopping rule, since we have the information on the expected accuracy or, alternatively, the probability of finding more accurate ensembles. Experimental analyses of the created ensembles of pattern classifiers and object detectors confirm the efficiency of our approach over other pruning ones. Moreover, we propose a novel stochastic search method that better fits the energy, which can be incorporated in other stochastic strategies as well.
