Abstract
The shift invariant multi-linear model based on
the CandeComp/PARAFAC (CP) model denoted ShiftCP has
proven useful for the modeling of latency changes in trial
based neuroimaging data[17]. In order to facilitate component
interpretation we presently extend the shiftCP model such that the
extracted components can be constrained to pertain to predefined
frequency ranges such as alpha, beta and gamma activity. To
infer the number of components in the model we propose to
apply automatic relevance determination by imposing priors that
define the range of variation of each component of the shiftCP
model and learning the hyper-parameters of these priors during
model estimation.
