The French meeting on Computational Geometry (JGA — Journées de Géométrie Algorithmique) will be 100% virtual this year, and will take place the afternoons (French time) from:

Monday May 30th to Wednesday June 1st 2022.

We invite contributed talks both in French and in English, and particularly encourage PhD students and early career researchers to give presentations on their work (see below for registration).

***** DESCRIPTION *****

The JGA conference is dedicated to uniting members of the French research community interested in Computational Geometry and related fields, including but not restricted to algorithms and computational complexity, geometric and topological data analysis, combinatorics, computer graphics, discrete geometry, optimal transport and geometric measure theory, among other areas.

The conference is especially geared towards creating an environment for young members of the research community, including PhD students and postdocs, to present their recent results and to interact with other researchers. One of the main goals is to foster and encourage new ideas in a welcoming setting.

This year, we are happy to announce 3 keynotes by invited speakers:

-) Marthe Bonamy (CNRS-LaBRI)

-) Arnau Padrol (IMJ-PRG)

-) Gabriel Peyré (CNRS-ENS)

***** REGISTRATION *****

Registration is FREE but MANDATORY. The registration is open until May 20th.

All of the information regarding JGA 2022, as well as the registration page, are available on the conference website:

https://project.inria.fr/jga2022/

Please feel free to distribute this announcement as widely as possible.

Some datasets are too small for standard statistical/data analysis to
accurately characterize the data. Others are extremely large and data
size reduction methods may be needed. One solution is to use
topological data analysis to simplify and/or visualize data. This
workshop will include both tutorials and research talks on topological
techniques for visualizing data.

This is an in-person workshop with a hybrid component for those who
wish to join virtually.

Free registration. Travel funds are available for speakers and
graduate students.

Dear all,

We would like to announce the Conference on the Mathematics of Complex Data in Stockholm on June 13-16, 2022, hosted by the Brummer & Partners MathDataLab at the Department of Mathematics at KTH Royal Institute of Technology in Stockholm.

The aim of the conference is to bring together leading experts in the field and highlight recent advances in mathematics related to data analysis and artificial intelligence. The conference is intended to cover a broad range of topics with emphasis on data analysis, including algebra and topology, probability and statistics, applied harmonic analysis, and optimization.

The following is a snippet of topics covered at the conference.
* Algebraic statistics
* Applied harmonic analysis
* Computational methods for complex data
* Control and optimisation in machine learning
* High-dimensional statistics
* Mathematics of deep learning
* Stochastic analysis in learning
* Topological data analysis

The list of our speakers includes Patrick Cheridito (ETH, Zurich), Anna Gilbert (University of Michigan), Kathryn Hess Bellwald (EPFL), Mauro Maggioni (Johns Hopkins University), Eric Moulines (Ecole Polytechnique), Bernd Sturmfels (Berkeley/MPI Leipzig), Joel Tropp (Caltech), and Sara van de Geer (ETH, Zurich).

The registration is open. For more details see https://www.mathdatalab.org/ .

We will also organize a poster session. You are very welcome to apply for contributing by presenting your poster. We are preparing a book of abstracts for the conference. To be included, we need the applications for the poster by April 30.
Here is a link to the application for the poster session: https://docs.google.com/forms/d/e/1FAIpQLSej0C68CEAZmdctAaAcq-TQ8fhQiJ7rIjZzdBg-eX6IoTrXsw/viewform?usp=pp_url

We are excited to welcome you to Stockholm this summer!

Best wishes from the organizing team, René Corbet

Please note:  A schedule for this meeting, along with titles and abstracts for the talks, has been posted on the meeting web page. 

There will be Problem Session at this workshop.  We encourage participation in this session and/or the submission of written problems that are relevant to the subject area of the meeting title. A list of problems will be compiled, and then posted some time after the meeting date.

A zoom link for the workshop will be sent to participants on the workshop mailing list. To be added to this mailing list (if you have not already done so), please send email to [email protected].

This meeting is organized by:

Rick Jardine, Western University, with John Healy, Leland McInnes and Colin Weir of the Tutte Institute.

We invite the Topological Data Analysis community to a book launch event for Gunnar Carlsson’s and Mikael Vejdemo-Johansson’s new book Topological Data Analysis with Applications. At the event, Justin Curry (SUNY Albany) will lead a fireside chat with Mikael Vejdemo-Johansson in a conversation about the research field, its history, community, and wider applicability. Copies of the book will be available to browse through, and participants interested in buying a copy can prepay at a discounted price of $40 (tax included). Prepaid books will be signed and delivered at the event.

CUNY requires all campus visitors to be fully vaccinated. In order to issue campus access passes, we need RSVP in advance.

When? Friday April 8, 5pm-7pm
Where? CUNY Graduate Center, 365 5th Avenue, NYC; Room 4201.
Order book by? March 24
RSVP by? March 29

RSVP and prepay here: https://www.eventbrite.com/e/book-launch-topological-data-analysis-with-applications-tickets-290959907917

After the event finishes, we are planning an afterparty at some cocktail bar in NYC. Indicate your interest with your RSVP.

The Vrije Unversiteit Amsterdam is advertising two tenure track positions. From the advertisement:

Our department is looking for mathematicians with a proven expertise in geometric and topological aspects of data and algorithms. This topic can be interpreted in a wide sense: we are interested in analytical, statistical, probabilistic and combinatorial ideas to deepen our understanding of the relation between geometric and topological ideas on the one hand, and data science and its algorithms on the other hand. Concrete subject fields include stochastic geometry, topological (methods in) data analysis, geometric aspects of statistical learning, reconstruction of manifolds from data, equivariant deep neural networks, and applications of these. Other combinations of geometry/topology and data/algorithms are also a possibility. In this position, you develop their own research line. The position of Assistant Professor is initially a tenure track position for five years. After four years, based on transparent criteria, we will take a decision on the tenure. The preferred starting date is on or before September 1, 2022.

I would like to bring four vacancies at Utrecht University in the Netherlands to your attention. Two of these are joint with the computer science department; possible themes include (but are not limited to) topological data analysis and homotopy type theory. Two further positions are joint with the physics department; possible themes include (but are not limited to) topological or conformal field theory or the study of topological phases of matter. In general, if your research touches physics or computer science, please do not hesitate to apply. 

The level of the positions is up to negotiation, ranging from a 5-year lecturer/researcher position to an associate professorship. The application deadline is March 14.
