Distance learning and e-learning material application rapidly increases in few years. Ministry of Education and Sport and European Social Fund have fi nanced many projects for e-learning material production in Slovenia lately. As a result we have many more or less quality e-learning materials. Authors analyzed diff erent types of communication in the contemporary publically available e-learning...

The role of kappa opioid receptor agonists in learning and memory is controversial. In the present study, the effects of U-50,488H on scopolamine-, mecamylamine- and dizocilpine-induced learning and memory impairments in rats were investigated. Scopolamine (3.3 mumol/kg s.c.), a muscarinic cholinergic antagonist, and mecamylamine (40 mumol/kg s.c.), a nicotinic cholinergic antagonist, significa...

This paper presents an ensemble learning algorithm for liver tumour segmentation from a CT volume in the form of U-Boost and extends the loss functions to improve performance. Five segmentation algorithms trained by the ensemble learning algorithm with different loss functions are compared in terms of error rate and Jaccard Index between the extracted regions and true ones. key words: CT image,...

We revisit resampling procedures for error estimation in binary classification in terms of U-statistics. In particular, we exploit the fact that the error rate estimator involving all learning-testing splits is a U-statistic. Therefore, several standard theorems on properties of U-statistics apply. In particular, it has minimal variance among all unbiased estimators and is asymptotically normal...
