Subject: Tensorlab+ Release

It is our pleasure to announce the release of Tensorlab+. Tensorlab+
is a reproducible research repository for tensor computations, built
on top of Tensorlab. It can be downloaded from The first release of Tensorlab+
includes the algorithms, auxiliary functions, and data needed to
recreate the results of 150+ experiments that are discussed in 34 of
our research papers, allowing the reproduction of 180+ figures and
tables. Moreover, we have included 32 tutorials and demos showing how
the proposed algorithms can be used in your own applications.

Subject: Computational Science and HPC, Spain, Jul 2022

This is an invitation for contributions for the Workshop on
Computational Science and HPC (CSHPC), to be held with ICCSA 2022,
July 4-7, 2022 in Malaga, Spain,

The CSHPC Workshop focuses on numerical and symbolic methods,
simulations, algorithms and tools (software and hardware) for
developing and running scientific computations. High Performance
Computing (HPC), scalability and numerical precision are important in
view of the computational requirements and data, which are generally
large. Related topics may involve system architectures supporting the
applications: massively parallel systems, GPUs, hybrid systems and
distributed (cluster, grid/cloud) environments. Apart from traditional
algorithms, problem solving tools further include techniques using
neural networks, machine learning and genetic algorithms. Applications
(not necessarily utilizing HPC) will be considered from areas
including computational physics, computational mathematics and
statistics, quantum physics, fluid dynamics, molecular dynamics,
materials science and nanotechnology.

Subject: New, Journal of Machine Learning

The editorial office announces the launching of a new journal: Journal
of Machine Learning . Although the
world is generally over-populated with journals, the field of machine
learning (ML) is one exception. In mathematics, there are almost no
recognized venues (other than conference proceedings) for publishing
work on ML. In AI for Science, ideally, one would like to publish the
work in leading scientific journals such as Physical Review
Letters. However, this is a difficult task at the stage of developing
methodologies. Although there are many conferences in ML-related
areas, publishing in journal form (without submission deadlines and
without serious page limitations) is still the preferred venue in many
disciplines, especially in mathematics and the sciences.

The objective for Journal of Machine Learning (JML) is to become a
leading journal in all areas related to ML, including algorithms and
theory for ML, as well as applications to science and AI. JML will
start as a quarterly publication. Considering the fact that ML is a
vast and fast- developing field, we will do our best to carry out a
thorough and responsive review process. To this end, we will have a
group of young and active managing editors who will handle the review
process, and a large, interdisciplinary group of experienced board
members who can offer quick opinions and suggest reviewers when
needed. JML is published by Global Science Press and sponsored by the
Center for Machine Learning Research, Peking University & AI for
Science Institute, Beijing. All articles in JML are open-access and
there is no charge for the authors. High quality papers on all
aspects of machine learning are welcome.
