Robustness to Sparse Adversarial Corruption in Arbitrary Linear Measurements: Beyond Exact Recovery

Vishal Halder, Alexandre Reiffers-Masson, Abdeldjalil AÃ¯ssa-El-Bey +1

Recovery from linear measurements under sparse adversarial corruption is typically formulated as an exact-recovery problem: one seeks structural conditions on $A$ (e.g., r…

Tight Convergence Rates for Online Distributed Linear Estimation with Adversarial Measurements

Nibedita Roy, Vishal Halder, Gugan Thoppe +4

We study mean estimation of a random vector $X$ in a distributed parameter-server-worker setup. Worker $i$ observes samples of $a_{i}^{⊤} X$ , where $a_{i}^{⊤}$ is the $i$ th row of a…
