Fúziós rendszerek optimalizációs kérdései

Absztrakt:

In this lecture, we show how the optimal setting of an ensemble-based

medical detector can improve the performance of the system. That is,

instead of the individually optimal parameter settings of the member

algorithms, we determine such a setting that maximizes the accuracy of the

ensemble. Our case study are ensembles composed for microaneurysm and

exudate detection on retinal images. The determination of the optimal

parameter setting is a very time demanding problem, especially

in fusion-based systems. Thus, we suggest several speedups in a stochastic

optimum search framework regarding the evaluation of the corresponding

special energy function. In other words, we also suggest some

modifications and tuning of stochastic search approaches for

ensemble-based image detectors evaluated on test databases.
