WebTo address this problem, in this article, we focus on parallel Tucker decomposition of dense tensors on distributed-memory systems. The proposed method uses hierarchical … WebAbstract. We approach the problem of estimating the parameters of a latent tree graphical model from a hierarchical tensor decomposition point of view. In this new view, the marginal probability table of the observed variables in a latent tree is treated as a tensor, and we show that: (i) the latent variables induce low rank structures in ...
