NASLOV: Pandemic era app development
--------------------------------------------------------

The presenter is going to talk about a technological approach to help slow the spread of SARS-COV-2 by simplifying and accelerating the process of notifying people who might have been exposed to the virus while preserving their privacy.
Key to end, control the spread in an epidemic is rapid identification and quarantine of the infected individuals, determination of whom they have had close contact within the previous days and decontamination of locations the infected individual has visited.
This process is labour intensive, susceptible to memory errors, and fraught with privacy concerns. But the main advantage in this era is the availability of smart-phones, mobile devices, and with the right technology we can overcome above difficulties and track down infected individuals in a much productive way.

NASLOV: Clustering class association rules to form a Compact and Meaningful Associative Classifier
---------------------------------------------------------------------------------------------------------------------------------------
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 of rules. To produce compact and accurate classifiers, such rules have to be grouped and pruned, so that only a reasonable number of them are presented to the end user for inspection and further analysis. To solve this problem researchers have proposed several associative classification approaches that combine two important data mining techniques, namely, classification and association rule mining.

In this research, we propose a new method that is 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. More precisely, we propose a new associative classifier – CMAC, that uses agglomerative hierarchical clustering as a post-processing step to reduce the number of its rules.

NASLOV: Interactive paper with back print illumination and rear-projection
-------------------------------------------------------------------------------------------------------------------------

POVZETEK:

We live in an era where our society remains to be heavily dependent on paper. The simplicity, sensory richness and versatility enabled the paper to maintain its importance in this digital age. However despite these obvious advantages of paper our lives are becoming more and more digital. This introduces a need for new solutions that will integrate digital technology with paper whilst maintaining its unique aforementioned properties. This talk presents the findings of a study of rear projection and back print illumination using paper as screen material.

PREDAVATELJICA: Elham MOTAMEDI
-------------------------------------------------

Elham Motamedi is a PhD student at UP FAMNIT. She completed her Master's degree of networked systems at the University of Tehran, Iran and her Bachelor's degree of information technology at the Isfahan University of Technology, Iran. Her research interests include multimedia and recommender systems.

--------------------------------------------------------------------------------
NASLOV: User-centric multimedia characteristics: A Survey
--------------------------------------------------------------------------------

The properties of multimedia content are usually represented as content-centered metadata, such as type (e.g. video, audio, text, etc.), duration, resolution, etc. However, in user-centric applications, such as personalized recommender systems, it makes more sense to describe multimedia items with user-centric meta-data, such as genre, emotions, etc. For example, a recommender system would make a better job of explaining recommendations in the form of "You have been recommended this film because you liked comedies" than "You have been recommended this film because you liked 1:30 long films". The problem of such a characterization is that it usually requires humans to annotate with user-centric metadata, which is expensive. Hence,  research efforts have been made to develop automatic methods for mapping multimedia content to user-centric item characteristics.
In this presentation, I present some of the state-of-the-art studies in studying automatic approaches for predicting user-centric characteristics of multimedia contents and some raw ideas of future work.

TITLE: NetsJSON - part 2
---------------------------------
ABSTRACT: 

A network consists of a graph and additional data on (properties of) nodes and/or links.
In some applications, the values of properties can be structured objects such us intervals, compositions, sets of keywords, temporal quantities, etc. Standard network description formats do not support such kinds of networks. 
We propose a JSON based format NetsJSON as a general network description option. It is supported in Python by a network analysis library Nets. The NetsJSON descriptions can be used as input data for network visualizations based on D3.js.
