abstract:
Multifold data structures are generally stored in high-dimensional objects
defined as nth-order tensors. Generalization of trilinear decompositions such as the
CANDECOMP/PARAFAC model can be used for modelling 4th order tensors. The
application of these techniques is, however, quite limited due to procedural com-
plexity and interpretational issues. These concerns increase when tensors contain
data with a compositional structure. This work aims at addressing these difficulties
through an application on Italian university staff.
