Subject: Scientific Computing and Machine Learning, Japan, Mar 2024

We are delighted to announce the call for papers for the International
Conference on Scientific Computing and Machine Learning (SCML2024, ), which will be held in Kyoto (and online) in Japan
from March 19 to 23, 2024.

In recent years, machine learning methods for scientific computing,
such as physics-informed neural networks and operator learning, have
attracted much attention. Many methods are based on machine learning
and/or theories of physics and/or computational mathematics. This
conference aims to showcase the latest research in these areas, which
have been fragmented while pursuing research in the same direction,
thereby bridging the gap between them and promoting collaboration.

The deadline for submission is January 7 (but it may be postponed for
a week or so.) For more information, please visit:

Institute for Computational and Experimental Research in Mathematics
(ICERM) at Brown University during July 22 - August 2, 2024. The
application is now open, and more information can be found from:

The goal of this two-week research and professional development
workshop is to support the retention and success of junior and
mid-career computational mathematicians who are from groups that are
underrepresented in the field. Participants will forge strong
collaborations in mentored research groups and engage in professional
development via no-lead learning communities. The larger goal of the
workshop is to form a positive, diverse community of researchers who
are committed to supporting each other's professional and scholarly

In research teams led by experienced mentors, participants will be
introduced to cutting-edge opportunities in numerical analysis and
scientific computing, and will actively work on and contribute to a
research project with their team. The supportive formal and informal
mentoring will help participants grow their scientific and
collaborative skills. In addition, the collaborative learning
communities will provide the participants with a forum for personal
and professional growth in their self-identified areas of need and
will deliver professional and leadership development in a small group
setting. The workshop will also include panels and discussions on a
range of issues including addressing intersectional issues involving
gender, race, and LGBTQ+ status in the profession.

This research collaborative effort is run in collaboration with SIAM
which will provide support for sustained interaction and collaboration
even beyond the two-week workshop.

mixed-integer programs as a part of a project associated with CEZ, the
largest utility in Central and Eastern Europe with extensive
activities in the generation, distribution, trade in, and sales of
electricity and heat, as well as trade in and sales of natural gas.

The student will be responsible for developing methods that are able
to efficiently track a solution of a mixed integer linear and
nonlinear programs as coefficients of the problem changes
continuously, analyzing their properties theoretically, and
implementing them in prototypes. The optimization problems arise in
mathematical models for unit commitment and trading power and
ancillary services in response to changing demand and order book. To
improve computational tractability, semidefinite relaxations of the
integer programs will be used, which transform the problem into a
convex one. Important details regarding the relationship of these
relaxations to the integer solutions, and the computational
implications, will be the focus of the PhD study.

The PhD student will be co-supervised by Vyacheslav Kungurtsev and
Jakub Marecek. A degree in mathematics, computer science, or similar,
proficiency in written and spoken English, and competence with
programming are expected of the applicant. If in interested, please
send a CV and motivation letter to
