Noisy and missing data regression: Distribution-oblivious support recovery
Y Chen, C Caramanis - International Conference on …, 2013 - proceedings.mlr.press
Many models for sparse regression typically assume that the covariates are known
completely, and without noise. Particularly in high-dimensional applications, this is often not …
