High Dimensional Structured Superposition Models

no code implementations NeurIPS 2016 Qilong Gu, Arindam Banerjee

High dimensional superposition models characterize observations using parameters which can be written as a sum of multiple component parameters, each with its own structure, e. g., sum of low rank and sparse matrices, sum of sparse and rotated sparse vectors, etc.
