Paper got accepted to the SIAM Optimization journal
One of the first papers that I wrote got accepted to the SIAM journal on optimization (SIOPT). The review process was quite long and included several revisions, but I’m happy I got it accepted before my graduation. This work is a result of my collaboration with J. Malick and F. Iutzeler, from whose experience I learned a lot about optimization. The title of the work is “A Distributed Flexible Delay-tolerant Proximal Gradient Algorithm”.

I got NeurIPS Travel Award
In addition to my free NeurIPS registration, which I received as on of the top reviewers, I will also receive $1400 from the NeurIPS Foundation to sponsor my travel to the conference.

Invited talk at Boris Polyak's seminar
I was invited by Boris Polyak to present my work on Sinkhorn algorithm at his seminar. The talk took place on Tuesday, 22 October, at the Institute of Control Sciences. It was a great pleasure to hear that Boris liked my work for its simplicity. The slides of my talk are now attached to the corresponding publication (https://konstmish.github.io/publication/19_sinkhorn/).

NeurIPS workshops: 5 accepted papers

We have submitted 5 papers to 4 different workshops hosted by NeurIPS and all of them were accepted, including one work for oral presentation. The list of papers:

  1. Stochastic Newton and Cubic Newton Methods with Simple Local Linear-Quadratic Rates (oral, with D. Kovalev and P. Richtárik)

  2. Sinkhorn Algorithm as a Special Case of Stochastic Mirror Descent (single-author work)

  3. Better Communication Complexity for Local SGD (with A. Khaled and P. Richtárik)

  4. First Analysis of Local GD on Heterogeneous Data (with A. Khaled and P. Richtárik)

  5. Revisiting Stochastic Extragradient (with D. Kovalev, E. Shulgin, Y. Malitsky and P. Richtárik)

NeurIPS workshops: 5 accepted papers
Paper accepted as spotlight to NeurIPS workshop 'Beyond First-Order Methods in ML'
We just got a notification that our paper (by D. Kovalev, P. Richtárik and me) was accepted to the NeurIPS workshop “Beyond First-Order Optimization Methods in Machine Learning” for a spotlight (8 minute talk) and poster presentation. Together with the free registration that I got as one of the top reviewers, this gives more than enough reason to attend the conference. We are also waiting for the decisions for our submissions to other workshops, so soon there might be more news!

A new paper which connects Sinkhorn Algorithm and Stochastc Mirror Descent
My new paper (for the first time I wrote a single authored work!) is now available online, see the publication section. It turned out the famous Sinkhorn algorithm is nothing but an instance of stochastic mirror descent. Very exciting to see the notion of relative smoothness appear as the only explanation of convergence from the mirror descent perspective.
