Metrizing Fairness
Daniel Kuhn, Yves Rychener, Bahar Taskesen
We study supervised learning problems for predicting properties of individuals who belong to one of two demographic groups, and we seek predictors that are fair according to statistical parity. This means that the distributions of the predictions within th ...
2022Unlocking crowding by ensemble statistics
Michael Herzog, David Pascucci, Oh-Hyeon Choung, Yury Markov, Natalia Tiurina
In crowding,1-7 objects that can be easily recognized in isolation appear jumbled when surrounded by other elements.8 Traditionally, crowding is explained by local pooling mechanisms,3,6,9-15 but many findings have shown that the global configuration of th ...
CELL PRESS2022HybridSDF: Combining Deep Implicit Shapes and Geometric Primitives for 3D Shape Representation and Manipulation
Pascal Fua, Nicolas Talabot, Subeesh Vasu, Artem Lukoianov
Deep implicit surfaces excel at modeling generic shapes but do not always capture the regularities present in manufactured objects, which is something simple geometric primitives are particularly good at. In this paper, we propose a representation combinin ...
2022Extremal Eigenvalues Of The Dirichlet Biharmonic Operator On Rectangles
We study the behaviour of extremal eigenvalues of the Dirichlet biharmonic operator over rectangles with a given fixed area. We begin by proving that the principal eigenvalue is minimal for a rectangle for which the ratio between the longest and the shorte ...
2020The uniform symbolic topology property for diagonally F-regular algebras
Let k be a field of positive characteristic. Building on the work of the second named author, we define a new class of k-algebras, called diagonally F-regular algebras, for which the so-called Uniform. Symbolic Topology Property (USTP) holds effectively. W ...
2020On the Volume of the John-Lowner Ellipsoid
We find an optimal upper bound on the volume of the John ellipsoid of a k-dimensional section of the n-dimensional cube, and an optimal lower bound on the volume of the Lowner ellipsoid of a projection of the n-dimensional cross-polytope onto a k-dimension ...
SPRINGER20203D Smith chart constant quality factor semi-circles contours for positive and negative resistance circuits
Mihai Adrian Ionescu, Andrei Müller
The article firstly proves that the constant quality factor (Q) contours for passive circuits, while represented on a 2D Smith chart, form circle arcs on a coaxal circle family. Furthermore, these circle arcs represent semi-circles families in the north he ...
2020The cup product of Brooks quasimorphisms
We prove the vanishing of the cup product of the bounded cohomology classes associated to any two Brooks quasimorphisms on the free group. This is a consequence of the vanishing of the square of a universal class for tree automorphism groups. ...
WALTER DE GRUYTER GMBH2018The effect of overall stimulus configuration on crowding
Michael Herzog, Maya Roinishvili, Mattew Pachai
The standard framework to study vision is typically hierarchical and feedforward, which facilitates deconstructing complex mechanisms into smaller, more tractable problems. However, this framework can fail when elements are presented in context, as they ar ...
2017The effect of “objecthood” in the Ebbinghaus illusion
Michael Herzog, Aline Françoise Cretenoud, Einat Rashal
In the Ebbinghaus illusion, observers overestimate the size of a target when it is surrounded by large flakers and compared with a control target surrounded by small flankers. We examined whether “objecthood” – the degree to which an object is a cohesive e ...
