Structure-revealing data fusion

Abstract: BackgroundAnalysis of data from multiple sources has the potential to enhance knowledge discovery by capturing underlying structures, which are, otherwise, difficult to extract. Fusing data from multiple sources has already proved useful in many applications in social network analysis, signal processing and bioinformatics. However, data fusion is challenging since data from multiple sources are often (i) heterogeneous (i.e., in the form of higher-order tensors and matrices), (ii) incomplete, and (iii) have bot… Show more

“…In order to fit the ACMTF model, we use ACMTF-OPT [15] from the CMTF Toolbox and the nonlinear conjugate gradient Parts of sr corresponding to the time samples for each electrode in EEG and voxels in fMRI and sMRI are plotted. In EEG plots, green dashed plots show signals from individual electrodes averaged across all subjects.…”
