Over-parameterization: A Necessary Condition for Models that Extrapolate

Roozbeh Yousefzadeh

In this work, we study over-parameterization as a necessary condition for having the ability for the models to extrapolate outside the convex hull of training set. We specifically,…

Federated Learning without Revealing the Decision Boundaries

Roozbeh Yousefzadeh

We consider the recent privacy preserving methods that train the models not on original images, but on mixed images that look like noise and hard to trace back to the original imag…
