Tilting the playing field: Dynamical loss functions for machine learning
Miguel Ruiz-Garcia, Ge Zhang, Samuel S. Schoenholz +1
We show that learning can be improved by using loss functions that evolve cyclically during training to emphasize one class at a time. In underparameterized networks, such dynamica…
Coherence Resonance and Stochastic Resonance in an Excitable Semiconductor Superlattice
Emanuel Mompo, Miguel Ruiz Garcia, Manuel Carretero +3
Collective electron transport causes a weakly coupled semiconductor superlattice under dc voltage bias to be an excitable system with degrees of freedom: electron densities…
Buckling of thermalized elastic sheets
Ali Morshedifard, Miguel Ruiz-Garcia, Mohammad Javad Abdolhosseini Qomi +1
Steady progress in the miniaturization of structures and devices has reached a scale where thermal fluctuations become relevant and it is thus important to understand how such fluc…
Fluctuation-induced current from freestanding graphene: toward nanoscale energy harvesting
P. M. Thibado, P. Kumar, Surendra Singh +3
At room temperature, micron-sized sheets of freestanding graphene are in constant motion even in the presence of an applied bias voltage. We quantify the out-of-plane movement by c…
Topologically controlled emergent dynamics in flow networks
Miguel Ruiz-Garcia, Eleni Katifori
Flow networks are essential for both living organisms and enginneered systems. These networks often present complex dynamics controlled, at least in part, by their topology. Previo…
Large-scale critical behavior of the rippling phase transition for graphene membranes
Tommaso Cea, Miguel Ruiz-Garcia, Luis Bonilla +1
We analyze the spontaneous rippling of graphene membranes as function of the coupling between lattice deformations and electrons. We numerically study a model of an elastic membran…
