Online workshop: Optimal transport, topological data analysis and applications to shape and machine learning

Dear all,

We wanted to bring to your attention an upcoming workshop — July 27 to
July 31 — on applied topology, optimal transport and machine learning.
These are rapidly-developing verticals with budding interactions that
some of you might find interesting. The workshop will be entirely
online, and hosted through MBI-Ohio State. More information on events,
schedule and how to register can be found here:

Subset of ATMCS talks hosted online by AATRN

Unfortunately, the ATMCS (Algebraic Topology: Methods, Computation, and Science) conference will not be happening in 2020. However, a subset of early-career ATMCS talks will be hosted in an online summer seminar series by AATRN (Applied Algebraic Topology Research Network). These talks were contributed and accepted for ATMCS, but this is not going to be ATMCS itself.

For a list of these ATMCS talks hosted by AATRN, please see our webpage:
https://tgda.osu.edu/atmcs2020/atmcs-2020-talks-hosted-by-the-aatn/
The majority of the talks will be on Mondays at 11am-12pm Eastern Times, starting Monday, May 25. We will have two speakers per week, with each speaker giving a 20 minute talk. The first speakers (on Monday, May 25) are Vincent Divol and Théo Lacombe, on Studying the space of Persistence Diagrams using Optimal Partial Transport.

If you want to attend these talks, then please become an AATRN member by clicking on the “members” tab at https://topology.ima.umn.edu/. We will send out one announcement email to all AATRN members per talk, including information for how to join the talk on Zoom. You will receive an email with the Zoom details for our first May 25 talk either later today, or within a day after you first join the network. If you have any difficulties joining or obtaining the Zoom details (or for example want the Zoom details for the first talk before becoming an AATRN member), then please send an email to aatrn.director@gmail.com.

Best,
Henry Adams and Sara Kalisnik, AATRN

Computational Geometry: Media Exposition — First Announcement

Please see the call below. Notice that this media track has expanded its definition to have a wider scope this year. We welcome your submissions!

Here is the corresponding webpage:

Computational Geometry: Media Exposition — First Announcement

=========================================================
Media, Visualizations, and Geometric Art are sought for the 29th International Computational Geometry Media Exposition (CG:ME), which will take place as part of Computational Geometry Week 2020, encompassing the 35th International Symposium on Computational Geometry. Submissions showcase creative approaches to illustrate research and/or support education in computational geometry. 

DATES
=====

All deadlines are 23:59 anywhere on earth.

  • February 21, 2020 Abstract and media portfolio submissions due
  • March 8, 2020 Notification of acceptance/rejection
  • March 30, 2020 Final version of abstract and portfolio
  • June 23-26, 2020 Computational Geometry Week

CONTENT
=======

  • The submission should be related to computational geometry, broadly interpreted, but is otherwise unrestricted: for example, it can illustrate a (new or existing) concept, technique or algorithm from computational geometry, it can explain an application of computational geometry, it can be meant for educational purposes or for entertainment purposes, and so on. 
  • The form of media is broad, including algorithm animations, interactive software and games, scientific artwork, sculptures, paintings, and virtual reality demonstrations. While videos are welcome, they are no longer required as in previous years.

SUBMISSION
==========

A submission consists of two parts: a portfolio and a paper.

  • Submit a portfolio of the work, such as images, video, link to interactive apps, etc.  The submission should still be “displayable” during CGweek, and the authors should specify in their submission how the piece will be displayed. For example, if it is about a geometry-inspired sculpture, then one can bring the sculpture itself, or submit a video about this sculpture, its story and its connection to computational geometry. Note that if your work is a video, then the portfolio and the work are in fact identical.
  • Submit a paper which details the portfolio and where applicable, the techniques used in the implementation. The paper should explain the connection of the submission to computational geometry, broadly interpreted.  
  • Acceptance is based on both the submitted portfolio and the accompanying paper.

Technical Details

  • Portfolio submissions are limited to 100 MB. Authors are free to post higher quality versions on their own web sites, and we will include links in the electronic proceedings to their version, in addition to the official version (<100 MB) archived on http://www.computational-geometry.org
  • Videos should be 720p or better, using H.264, where the embedded audio stream should be AAC of at least 128kBit/s.
  • The paper must be formatted according to the guidelines for the conference proceedings using the LIPIcs format, and not exceed 100 lines, excluding front matter and references.  The number of images in the paper should also be kept reasonable. Typesetting instructions and the .cls style file are available on the CG website: http://www.computational-geometry.org

EVENT
=====

  • The Work will be on display at a gallery during Computational Geometry Week.  
  • The authors will have a session devoted to giving a short talk on their work at the Symposium on Computational Geometry.

COMMITTEE
=========

  • Henry Adams, Colorado State University, USA
  • Jit Bose, Carleton University, Canada
  • Satyan Devadoss (chair), University of San Diego, USA
  • David Eppstein, University of California, Irvine, USA
  • John McCleary, Vassar College, USA

Postdoc positions in Topological Data Analysis at KTH

The mathematics department at KTH offers up to two, two years, postdoc positions to join the Topological Data Analysis group. The TDA group currently consists of two faculty members: Wojciech Chacholski and Martina Scolamiero, one postdoc Rayan Ramanujan and three PhD students: Oliver Gavfert, Francesca Tombari and Alvin Jin. We work on a variety of topics including: studying the topology of decompositions of simplicial complexes, defining and computing stable invariants for multi-persistence, applications of TDA to machine learning and neuroscience. Furthermore KTH offers an inclusive and exciting atmosphere with plenty of opportunities to collaborate for example with the algebraic geometry group, researchers working on mathematical foundations of A.I, the Brummer & Partners MathDataLab and the WASP program. Although in the announcement it is stated that a PhD is required to apply, we are going to  consider applications of everyone who will graduate before the start of the position. 

The application deadline is 20 January 2020. For more information on the position and the application process please follow the link:
