Estimation of sparse linear regression coefficients under $L$-subexponential covariates

However, these methods require stronger conditions than those used for Gaussian random vectors to derive the error bounds.

Outlier Robust and Sparse Estimation of Linear Regression Coefficients

no code implementations24 Aug 2022 Takeyuki Sasai, Hironori Fujisawa

We consider outlier-robust and sparse estimation of linear regression coefficients, when the covariates and the noises are contaminated by adversarial outliers and noises are sampled from a heavy-tailed distribution.

We consider a robust estimation of linear regression coefficients.

Adversarial Robust Low Rank Matrix Estimation: Compressed Sensing and Matrix Completion

no code implementations25 Oct 2020 Takeyuki Sasai, Hironori Fujisawa

We deal with matrix compressed sensing, including lasso as a partial problem, and matrix completion, and then we obtain sharp estimation error bounds.

Robust estimation with Lasso when outputs are adversarially contaminated

no code implementations13 Apr 2020 Takeyuki Sasai, Hironori Fujisawa

Nguyen and Tran (2012) proposed an extended Lasso for robust parameter estimation and then they showed the convergence rate of the estimation error.
