A local Wheeler-DeWitt measure for the string landscape

open access: yesNuclear Physics B, 2023
According to the ‘Cosmological Central Dogma’, de Sitter space can be viewed as a quantum mechanical system with a finite number of degrees of freedom, set by the horizon area.

Central quantile subspace [PDF]

open access: yesStatistics and Computing, 2019
Quantile regression (QR) is becoming increasingly popular due to its relevance in many scientific investigations. There is a great amount of work about linear and nonlinear QR models. Specifically, nonparametric estimation of the conditional quantiles received particular attention, due to its model flexibility.

Statistical multi-level shape models for scalable modeling of multi-organ anatomies

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Statistical shape modeling is an indispensable tool in the quantitative analysis of anatomies. Particle-based shape modeling (PSM) is a state-of-the-art approach that enables the learning of population-level shape representation from medical imaging data

Central Subspaces of Banach Spaces

open access: yesJournal of Approximation Theory, 2000
Let \(X\) be a Banach space. A subspace \(Y \subset X\) is called a central subspace (\(C\)-subspace) of \(X\) if every finite family of closed balls with centers in \(Y\) that intersects in \(X\) also intersects in \(Y\). In particular \(X\) is said to be generalized center (GC) if and only if \(X\) is a \(C\)-subspace of \(X^{**}\).

Intersection Properties of Balls in Banach Spaces

open access: yesJournal of Function Spaces and Applications, 2013
We introduce a weaker notion of central subspace called almost central subspace, and we study Banach spaces that belong to the class (GC), introduced by Veselý (1997). In particular, we prove that if is an almost central subspace of a Banach space such

Combined central and subspace clustering for computer vision applications [PDF]

open access: yesProceedings of the 23rd international conference on Machine learning - ICML '06, 2006
Central and subspace clustering methods are at the core of many segmentation problems in computer vision. However, both methods fail to give the correct segmentation in many practical scenarios, e.g., when data points are close to the intersection of two subspaces or when two cluster centers in different subspaces are spatially close. In this paper, we
