In particular, we propose a method for the principled selection of the threshold value for functional network reconstruction from raw data, and for proper identification of the network's indicators that unveil the most discriminative information on the system for classification purposes. We illustrate our method by analysing networks of functional brain activity of healthy subjects, and patients suffering from Mild Cognitive Impairment, an intermediate stage between the expected cognitive decline of normal aging and the more pronounced decline of dementia. We discuss extensions of the scope of the proposed methodology to network engineering purposes, and to other data mining tasks. date: 2012-09-05 date_type: published publisher: Nature Publishing Group official_url: http://www.nature.com/srep/2012/120905/srep00630/full/srep00630.html id_number: 10.1038/srep00630 full_text_status: public publication: Scientific Reports volume: 2 number: 630 pagerange: 1-4 institution: Tecnologia_Biomedica department: otro refereed: TRUE issn: 2045-2322 rights: by-nc-nd citation: Zanin, Massimiliano and Sousa, Pedro and Papo, David and Bajo Breton, Ricardo and García Prieto, Juan and Pozo, Francisco del and Menasalvas Ruiz, Ernestina and Boccaletti, Stefano (2012).
