>> *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
