C 3 APTION: Constraint Coupled CP And PARAFAC2 Tensor Decompostion

Given data from a variety of sources that share a number of dimensions, how can we effectively decompose them jointly into interpretable latent factors? The coupled tensor decomposition framework captures this idea by jointly supporting the decomposition of several CP tensors. However, coupling tends to suffer when one dimension of data is irregular, i.e., one of the dimensions of the tensor is un...
