Rethinking data augmentation for adversarial robustness
Recent work has proposed novel data augmentation methods to improve the adversarial robustness of deep neural networks. In this paper, we re-evaluate such methods through the lens of different metrics that characterize the augmented manifold, finding contr ...
2023Role of stochastic noise and generalization error in the time propagation of neural-network quantum states
Neural-network quantum states (NQS) have been shown to be a suitable variational ansatz to simulate out-of-equilibrium dynamics in two-dimensional systems using timedependent variational Monte Carlo (t-VMC). In particular, stable and accurate time propagat ...
SCIPOST FOUNDATION2022From SU(2)5 to SU(2)3 Wess-Zumino-Witten transitions in a frustrated spin-52 chain
Frédéric Mila, Natalia Chepiga
We investigate the properties of a frustrated spin-5/2 chain with next-nearest-neighbor two- and three-site interactions, with two questions in mind: the nature of the transition into the dimerized phase induced by the three-site interaction, and the possi ...
