Hyperparameter Optimisation in Deep Learning from Ensemble Methods: Applications to Proton Structure
Juan Cruz-Martinez, Aaron Jansen, Gijs van Oord +4
Deep learning models are defined in terms of a large number of hyperparameters, such as network architectures and optimiser settings. These hyperparameters must be determined separ…
Holographic Bubbles with Jecco: Expanding, Collapsing and Critical
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +4
Cosmological phase transitions can proceed via the nucleation of bubbles that subsequently expand and collide. The resulting gravitational wave spectrum depends crucially on the pr…
Spinodal Gravitational Waves
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +5
We uncover a new gravitational-wave production mechanism in cosmological, first-order, thermal phase transitions. These are usually assumed to proceed via the nucleation of bubbles…
Quasinormal modes in charged fluids at complex momentum
Aron Jansen, Christiana Pantelidou
We investigate the convergence of relativistic hydrodynamics in charged fluids, within the framework of holography. On the one hand, we consider the analyticity properties of the d…
Entropy production and entropic attractors in black hole fusion and fission
Tomas Andrade, Roberto Emparan, Aron Jansen +3
We study how black hole entropy is generated and the role it plays in several highly dynamical processes: the decay of unstable black strings and ultraspinning black holes; the fus…
Entropy production from quasinormal modes
Aron Jansen, Ben Meiring
Horizons of black branes have an associated entropy current with non-negative divergence. We compute this divergence in a late-time transseries expansion for an inhomogeneous syste…
