The Franz-Parisi Criterion and Computational Trade-offs in High Dimensional Statistics

NeurIPS 2022accept

Many high-dimensional statistical inference problems are believed to possess inherent computational hardness. Various frameworks have been proposed to give rigorous evidence for such hardness, including lower bounds against restricted models of computation (such as low-degree functions), as well as…

Overcomplete Independent Component Analysis via SDP

AISTATS 2019poster

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 algorithms either suffer from high computational complexity or make strong assumptions about the form of the mixing matrix…
