Fast algorithms for the minimum volume estimator

SD Ahipaşaoğlu - Journal of Global Optimization, 2015 - Springer
The minimum volume ellipsoid (MVE) estimator is an important tool in robust regression and
outlier detection in statistics. We develop fast and efficient algorithms for the MVE estimator …

Poincaré fréchet mean

X Cao - Pattern Recognition, 2023 - Elsevier
Generalizing the Fréchet mean from the Euclidean metric is not able to properly capture the
geometric characteristics of many non-trivial operations, such as the non-dot inner product …

Fast and robust approximation of smallest enclosing balls in arbitrary dimensions

T Larsson, L Källberg - Computer Graphics Forum, 2013 - Wiley Online Library
In this paper, an algorithm is introduced that computes an arbitrarily fine approximation of
the smallest enclosing ball of a point set in any dimension. This operation is important in, for …

Minimum enclosing balls and ellipsoids in general dimensions

L Källberg - 2019 - diva-portal.org
In this doctoral thesis, we study the problem of computing the ball of smallest radius
enclosing a given set of points in any number of dimensions. Variations of this problem arise …
