Our upcoming AISTATS 2019 papers: @frejohk's "Support and Invertibility in Domain-Invariant Representations" & @apodosin's "Overcomplete Independent Component Analysis via SDP" (both to be posted soon), & Hunter Lang's "Block Stability for MAP Inference" (https://arxiv.org/abs/1810.05305 )
Does the ICA paper still use tensor decomposition in overcomplete setting?

Great to hear from you. It works with generalized covariance matrices, and then iteratively solves for mixing components by optimizing an SDP using projected accelerated gradient descent, followed by deflation.
