Jamolbek Mattiev obtained his PhD degree in Computer Science at UP FAMNIT. He got his Master degree in Computer Science from National University of Uzbekistan and was awarded with first degree diploma at “the best Master Dissertation Work of Uzbekistan” competition in his master studies. He also studied at Turin Polytechnic University (Italy) in his master study as an exchange student. He is doing his research in the field of Data Mining. His research fields include Artificial Intelligence, Data Mining, Machine Learning. In particular, the sub-fields of Supervised and Unsupervised Learning, Frequent Pattern Discovery, Association Rule Learning, Classification and Clustering.

NASLOV: The effect of distance metric "directness" on class association rules
----------------------------------------------------------------------------------------------------------
POVZETEK:
Huge amounts of data are being collected and analyzed nowadays. By using the popular rule-learning algorithms, the number of rules discovered on those big datasets can easily exceed thousands. To produce compact and accurate classifiers, such rules have to be grouped and pruned. To group the rules, we need appropriate distance metrics, because distance metrics are very important in clustering applications. To solve the above-mentioned problem, we present new methods (use different distance metrics) that are able to reduce the number of class association rules produced by classical class association rule classifiers, while maintaining an accurate classification model that is comparable to the ones generated by state-of-the-art classification algorithms. We also present how distance metrics are affecting the clustering of class association rules.
Experimental results performed on selected datasets from the UCI ML repository show that our methods are able to learn classifiers containing significantly less rules than state-of-the-art rule learning algorithms on datasets with larger number of examples. On the other hand, classification accuracies of the newly developed methods are not significantly different from state-of-the-art rule-learners on most of the datasets.

Marko Novak je študent magistrskega študijskega programa Računalništvo in informatika na UP FAMNIT. Trenutno se, poleg rednega dela na področju menedžmenta v gostinstvu in turizmu ter projektnega vodenja, ukvarja z magistrskim delom, v katerem skuša razviti mobilno aplikacijo za pametno obveščanje strank o prostih terminih.

NASLOV: Potisna obvestila in njihova uporaba v sodobnih sistemih obveščanja
----------------------------------------------------------------------------------------------------------
POVZETEK:
Sodobni informacijski sistemi nudijo uporabnikom vse več in več koristnih informacij na vseh področjih. Prav zaradi tako velike količine podatkov so sistemi obveščanja ključni za učinkovito komunikacijo z uporabniki. Vsi si želimo, da bi podatki, ki jih prejemamo bili kar se da uporabni in pravočasni, hkrati pa tudi nemoteči. Na seminarju bodo predstavljena potisna obvestila, kot eden od možnih načinov obveščanja v sodobnih informacijskih sistemih.
---------------------------------------------------------------------------------------------------
Predstavitev v okviru Ponedeljkovega seminarja računalništva in informatike se šteje kot del obveznosti pri predmetu Raziskovalni seminar II.
Predavanje bo potekalo v slovenskem jeziku prek spletnega orodja Zoom.
