Setting-up and changing the data model is done directly within the data model graph using a context menu to create and edit the fundamental semantic objects.
Total MRI duration was around 60 min in Experiment 1 and 100 min in Experiment 2. FMRI data pre-processing and statistical modeling was done in SPM8 (Wellcome Department of Cognitive Neuroscience, University College, London, UK).
40 Although the results of the VITAL-1 study were known when the modeling was done, the data of this study were not used to construct the model, thereby showing that modeling of short-term data can be used to anticipate the outcome of a complex clinical trial.
Specifically, with the aid of the compressed sensing concepts, compression of inter-node correlated data without using their correlation model is done in [22, 23].
The empirical estimation of the model is done using data from the Global entrepreneurship Monitor (GEM) database.
The whole process, from importing data to tagging it and training the model, is done through a drag and drop interface.
Also, the evaluation of the models is done with real data from online discussion platforms of very diverse nature: online forums (Y! Groups, Usenet), social news (Slashdot, Barrapunto, Digg, Reddit, Menéame), peer production (Wikipedia), social networks (Facebook, Google Plus), and microblogging services (Twitter).
For datasets A and B, we used the following strategy to split the data: training of the models was done on five persons (1300 data samples) and the remaining person (260 samples) was used for evaluation of the accuracy of predictions.
SAS, version 9.1, was used for all data analysis; all economic modelling was done in Treeage Pro 2009.
