>>> *Title:*           Communication-Efficient Distributed Optimization for
>>> Machine Learning
>>>
>>> *Abstract:    *In the quest for high accuracy machine learning models,
>>> both the size of the model and consequently the amount of data necessary to
>>> train the model have been hugely increased over time. Because of this,
>>> performing the learning process on a single machine is often infeasible. In
>>> a typical scenario of distributed learning, the training data is spread
>>> across different machines, and thus the process of training is done in a
>>> distributed manner. Another scenario, most common to federated learning, is
>>> when training data is inherently distributed across a large number of
>>> mobile edge devices due to data privacy concerns. Therefore, large-scale
>>> distributed optimization has become the default tool for the training of
>>> supervised machine learning models with a large number of parameters and
>>> training data.

>>> *Bio:  *Mher Safaryan is a postdoctoral fellow at King Abdullah
>>> University of Science and Technology (KAUST) in Saudi Arabia, working on
>>> Optimization for Machine Learning in the group supervised by Prof. Peter
>>> Richtárik. Previously, he worked with Prof. Diogo Gomes as a research
>>> technician at KAUST on Computer Algebra for Differential Equations. He did
>>> his Ph.D. in Mathematics at Yerevan State University (YSU) in Armenia,
>>> under the supervision of Prof. Grigori Karagulyan. His interests includes
>>> optimization, machine learning, and compressed communication
