Overcomplete Independent Component Analysis via SDP
Anastasia Podosinnikova, Amelia Perry, Alexander Wein +3
We present a novel algorithm for overcomplete independent components analysis (ICA), where the number of latent sources k exceeds the dimension p of observed variables. Previous al…
Beyond CCA: Moment Matching for Multi-View Models
Anastasia Podosinnikova, Francis Bach, Simon Lacoste-Julien
We introduce three novel semi-parametric extensions of probabilistic canonical correlation analysis with identifiability guarantees. We consider moment matching techniques for esti…
Rethinking LDA: moment matching for discrete ICA
Anastasia Podosinnikova, Francis Bach, Simon Lacoste-Julien
We consider moment matching techniques for estimation in Latent Dirichlet Allocation (LDA). By drawing explicit links between LDA and discrete versions of independent component ana…
Robust PCA: Optimization of the Robust Reconstruction Error over the Stiefel Manifold
Anastasia Podosinnikova, Simon Setzer, Matthias Hein
It is well known that Principal Component Analysis (PCA) is strongly affected by outliers and a lot of effort has been put into robustification of PCA. In this paper we present a n…
