Understanding the Decision Boundary of Deep Neural Networks: An Empirical Study
David Mickisch, Felix Assion, Florens Greßner +2
Despite achieving remarkable performance on many image classification tasks, state-of-the-art machine learning (ML) classifiers remain vulnerable to small input perturbations. Espe…
Non-standard gravitational waves imply gravitational slip: on the difficulty of partially hiding new gravitational degrees of freedom
Ignacy Sawicki, Ippocratis D. Saltas, Mariele Motta +2
In many generalized models of gravity, perfect fluids in cosmology give rise to gravitational slip. Simultaneously, in very broad classes of such models, the propagation of gravita…
A general mass term for bigravity
Giulia Cusin, Ruth Durrer, Pietro Guarato +1
We introduce a new formalism to study perturbations of Hassan-Rosen bigravity theory, around general backgrounds for the two dynamical metrics. In particular, we derive the general…
Inflationary perturbations in bimetric gravity
Giulia Cusin, Ruth Durrer, Pietro Guarato +1
In this paper we study the generation of primordial perturbations in a cosmological setting of bigravity during inflation. We consider a model of bigravity which can reproduce the…
Gravitational waves in bigravity cosmology
Giulia Cusin, Ruth Durrer, Pietro Guarato +1
In this paper we study gravitational wave perturbations in a cosmological setting of bigravity which can reproduce the ΛCDM background and large scale structure. We show that in ge…
New Gravitational Scales in Cosmological Surveys
Tessa Baker, Pedro G. Ferreira, C. Danielle Leonard +1
In the quasistatic regime, generic modifications to gravity can give rise to novel scale-dependence of the gravitational field equations. Crucially, the detectability of the new sc…
