2. 1. Organization of information pathways in complex networks

   Author : Atieh Mirshahvalad; Martin Rosvall; Santo Fortunato; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex systems; Complex Networks; Information; Communication; Community Detection; Significance Analysis; Resampling; Information Spreading.; computer and systems sciences; data- och systemvetenskap;

   Abstract : A shuman beings, we are continuously struggling to comprehend the mechanism of dierent natural systems. Many times, we face a complex system where the emergent properties of the system at a global level can not be explained by a simple aggregation of the system's components at the micro-level.

4. 2. Multivariate Networks : Visualization and Interaction Techniques

   Author : Ilir Jusufi; Andreas Kerren; Jessie Kennedy; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information Visualization; Multivariate Networks; Visual Analytics; Exploration; Interaction; Computer Science; Datavetenskap; Information and software visualization; Informations- och programvisualisering;

   Abstract : As more and more data is created each day, researchers from different science domains are trying to make sense of it. A lot of this data, for example our connections to friends on different social networking websites, can be modeled as graphs, where the nodes are actors and the edges are relationships between them.

5. 3. Predictive Techniques and Methods for Decision Support in Situations with Poor Data Quality

   Author : Rikard König; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rule Extraction; Genetic Programming; Uncertainty estimation; Machine Learning; Artificial Neural Networks; Data Mining; Information Fusion; Information technology; Informationsteknik; Teknik; Technology;

   Abstract : Today, decision support systems based on predictive modeling are becoming more common, since organizations often collect more data than decision makers can handle manually. Predictive models are used to find potentially valuable patterns in the data, or to predict the outcome of some event. READ MORE

6. 4. Information Technology Alignment : The Role of Organisational Structure

   Author : Gideon Mekonnen Jonathan; Lazar Rusu; Erik Perjons; Björn Johansson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer and Systems Sciences; data- och systemvetenskap; informationssystem; Information Systems;

   Abstract : Information technology (IT) alignment studies which focus on conceptual debates have left little room for studies investigating practical issues such as organisational structure. On the other hand, the attention paid to private and commercial organisations has resulted in findings that might not apply to public organisations. READ MORE

7. 5. Utilizing Diversity and Performance Measures for Ensemble Creation

   Author : Tuve Löfström; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; Computer science; Datavetenskap; Teknik; Technology;

   Abstract : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. READ MORE
