The WinCompTop@ATMCS event, organized by Erin Chambers, Ellen Gasparovic, and Yusu Wang, will be held June 6-7 at The Ohio State University.  Any member of the community (man or women) is welcome and encouraged to join us for this meeting.  In addition to talks by participants from the prior WinCompTop workshops and members of the community, there will also be a panel discussion, a dinner or social event, and open time for working groups to meet (or start new projects).  Funding is available to help with travel, particularly for junior participants.  

If you were a participant of one of the first two workshops and would be interested in talking about your group’s project or follow-up work, please get in touch with an organizer! 

After scheduling these talks, we plan to add additional talk slots for members of the community, but we hoped to first showcase some of the fantastic research that came out of WinCompTop 1 and 2.

Stay tuned for funding details and a program soon, and we hope to see many of you there!

Abstract:

This workshop at the University of Sydney will bring together experts and emerging researchers from Australia, the USA and Europe to report on recent results and explore future directions in computational and algorithmic topology and related areas. There will be a focus on problems in computational geometric topology and computational algebraic topology. This workshop aims to stimulate interaction between researchers in order to bring about new collaborations on difficult problems that cannot be tackled from one viewpoint alone.

We plan to have talks by our invited speakers in the mornings, and open problem sessions, a poster session, and plenty of time for collaboration in the afternoons.

Invited Speakers:

Herbert Edelsbrunner (Institute of Science and Technology Austria)
Brittany Fasy (Montana State University)
Gregory Henselman (Princeton University)
Feng Luo (Rutgers University)
Zuzana Patáková (Institute of Science and Technology Austria)
Jessica Purcell (Monash University)
Vanessa Robins (Australian National University)

Organizers:

Jonathan Spreer (The University of Sydney)Stephan Tillmann (The University of Sydney)

“AI & Topology” at the Applied Machine Learning Days 2020, EPFL

This year’s Applied Machine Learning Days will take place on January 27-29, 2020 at EPF Lausanne (Switzerland).  The goal of this conference is to bring together the best people in the field to talk about a variety of topics in the practice of machine learning — from technical developments to applications in social, scientific or other domains.  Previous editions featured keynote speakers such as Jeff Dean and Christopher Bishop, researchers from academic institutions and industry (Google AI and DeepMind, Facebook AI, IBM Research, Microsoft Research, and others), as well as public figures such as Zeynep Tufekci and Garry Kasparov.

This is the fourth iteration of the event, with more than 1500 people expected to attend each day this time.  The event will feature more than 20 domain-specific tracks and, over the weekend preceding the main event, a set of workshops, challenges, and other “hands-on” events.

L2F and the Laboratory for Topology and Neuroscience have the pleasure to announce this year’s AI & Topology track which will take place on Tuesday 28 January.  The purpose of the track is to showcase a variety of successful ideas and concrete applications of topology, geometry or other abstract mathematics to machine learning and data analysis.  It will feature the following speakers:

• Kathryn Hess Bellwald (EPFL)
• Frédéric Chazal (Inria)
• Vitaliy Kurlin (University of Liverpool)
• Bastian Rieck (ETH)
• Leland McInnes (Tutte Institute)
• Nicole Sanderson (LBNL)

Additionally, there will be a panel discussion with a Q&A session. The talks will be uploaded to YouTube soon after the event.

A range of tickets for the AMLD event (including discounts for students, academics, non-profits and startups) are still available here.

  Stochastic Topology

  TU Berlin (Germany), March 16-20, 2020

Block Course Lecturers:
———————–

  Omer Bobrowski (Technion)
  Matthew Kahle (Ohio State, TU Berlin)
  J. Andrew Newman (TU Berlin)
  Yuval Peled (NYU Courant Institute)

Scope:
——

Stochastic topology began in the mid-twentieth century with the study
of random graphs, that is, random 1-dimensional spaces. More recently,
several models of random high-dimensional simplicial complexes have been
introduced. Some of the most important questions in stochastic topology
have to do with establishing thresholds for various topological properties
within these models. This course will begin with an overview of the
standard combinatorial and geometric models, and then we will explore
some of the techniques that have been used to study them.

The block course is organized within the third Berlin Thematic Einstein
Semester on the “Geometric and Topological Structure of Materials”,
devoted to recent developments in the field of computational materials science.

The program will consist of short talks given by the participants and three lecture series by invited speakers. This year’s invited speakers are Kathryn Hess (EPFL), Thomas Nikolaus (WWU Münster) and Karen Vogtmann (Cornell University and University of Warwick).

More information will be available soon on the conference website https://sites.google.com/view/ytm2020. The registration is now open.
