Debiasing Distributed Second Order Optimization with Surrogate Sketching and Scaled Regularization
Michał Dereziński, Burak Bartan, Mert Pilanci +1
In distributed second order optimization, a standard strategy is to average many local estimates, each of which is based on a small sketch or batch of the data. However, the local…

Distributed Averaging Methods for Randomized Second Order Optimization
Burak Bartan, Mert Pilanci
We consider distributed optimization problems where forming the Hessian is computationally challenging and communication is a significant bottleneck. We develop unbiased parameter…

Distributed Sketching Methods for Privacy Preserving Regression
Burak Bartan, Mert Pilanci
In this work, we study distributed sketching methods for large scale regression problems. We leverage multiple randomized sketches for reducing the problem dimensions as well as pr…
