Pdf A Simple And Optimal Sublinear Algorithm For Mean Estimation View a pdf of the paper titled simple and optimal sublinear algorithms for mean estimation, by beatrice bertolotti and 3 other authors. We give sublinear time approximation algorithms for some optimization problems arising in machine learning, such as training linear classifiers and finding minimum enclosing balls.
Sublinear Time Algorithm Pdf Time Complexity Mathematical Relations To compute a solution efficiently, we design a novel and simple gradient descent algorithm that is significantly faster for our specific setting than all other known algorithms for computing geometric medians. In this section, we show that the geometric median of means estimator has an optimal sample complexity and give a gradient descent algorithm (algorithm 2) for computing a sufficiently good estimate efficiently. Our main contributions are two algorithms that estimate the mean of a point set and that have optimal sample com plexity. in addition, the running times are almost linear in the sample complexity and thus nearly optimal. Our main contributions are two algorithms that estimate the mean of a point set and that have optimal sample complexity. more importantly, they run in sublinear time and one of them has near optimal running time.

This work describes sub gaussian mean estimators for possibly heavy tailed data in both the univariate and multivariate settings and focuses on estimators based on median of means techniques, but other methods such as the trimmed mean and catoni's estimators are also reviewed.

Abstract: we study the sublinear multivariate mean estimation problem in $d$ dimensional euclidean space. specifically, we aim to find the mean $\mu$ of a ground point set $a$, which minimizes the sum of squared euclidean distances of the points in $a$ to $\mu$.
