Gradient Coding through Iterative Block Leverage Score Sampling

no code implementations6 Aug 2023 Neophytos Charalambides, Mert Pilanci, Alfred Hero

This is then used to derive an approximate coded computing approach for first-order methods; known as gradient coding, to accelerate linear regression in the presence of failures in distributed computational networks, \textit{i. e.} stragglers.

Dimensionality Reduction for $k$-means Clustering

no code implementations26 Jul 2020 Neophytos Charalambides

We present a study on how to effectively reduce the dimensions of the $k$-means clustering problem, so that provably accurate approximations are obtained.
