ShiftCP
The shiftCP model as described in M. Mørup et al. “Shift Invariant Multilinear Decomposition of Neuroimaging Data” NeuroImage 2008. The model is a generalization of the Canonical Decomposition/PARAFAC (CP)model to include temporal shifts that are specific to a given mode of the tensor.

ConvCP
The Convolutive CP model is a generalization of the Canonical Decomposition/PARAFAC (CP) model to include latency and shape changes. The model includes an implementation of automatic relevance determination in order to determine model order. The method is described in M. Mørup, K. H. Madsen, L. K. Hansen “Modeling trial based neuromaging data”, NIPS 2008 workshop on New Directions in Statistical Learning for Meaningful and Reproducible fMRI Analysis and M. Mørup, L.K. Hansen, K. H. Madsen “Modeling Latency and Shape Changes in Trial Based Neuroimaging Data”, ASILOMAR-SSC 2011.

Automatic Relevance Determination for CP and Tucker
This demo implements automatic relevance determination for the CP and Tucker models as described in our article M. Mørup and L. K. Hansen “Automatic Relevance Determination for Multiway Models”, Journal of Chemometrics. The code infers the number of components of the CP and Tucker model at the computational cost of fitting one ordinary model. (download .zip file)
Bayesian Community Detection
This software implement our extension of the IRM model to enforce community structure in complex networks as described in our article entitled M. Mørup and M. N. Schmidt “Bayesian Community Detection” submitted to Neural Computation.
