Semantic Perturbations with Normalizing Flows for Improved Generalization

Oguz Kaan Yuksel, Sebastian U. Stich, Martin Jaggi +1

Data augmentation is a widely adopted technique for avoiding overfitting when training deep neural networks. However, this approach requires domain-specific knowledge and is often…

Stochastic continuum armed bandit problem of few linear parameters in high dimensions

Hemant Tyagi, Sebastian Stich, Bernd Gärtner

We consider a stochastic continuum armed bandit problem where the arms are indexed by the $ℓ_{2}$ ball $B_{d} (1 + ν)$ of radius $1 + ν$ in $R^{d}$ . The reward functions $r :B_{…
