Subject: New Book, Nonnegative Matrix Factorization
Nonnegative matrix factorization (NMF) in its modern form has become a
standard tool in the analysis of high-dimensional data sets. This book
provides a comprehensive and up-todate account of the most important
aspects of the NMF problem and is the first to detail its theoretical
aspects, including geometric interpretation, nonnegative rank,
complexity, and uniqueness. It explains why understanding these
theoretical insights is key to using this computational tool
effectively and meaningfully.
Nonnegative Matrix Factorization
- is accessible to a wide audience and is ideal for anyone interested
in the workings of NMF,
- discusses some new results on the nonnegative rank and the
identifiability of NMF, and
- makes available MATLAB codes for readers to run the numerical
examples presented in the book.

Subject: New Book, Numerical Homogenization by Localized Decomposition
Check out SIAM's book, Numerical Homogenization by Localized
Decomposition by Axel Malqvist and Daniel Peterseim.
https://bookstore.siam.org/SL05
This book presents the first survey of the Localized Orthogonal
Decomposition (LOD) method, a pioneering approach for the numerical
homogenization of partial differential equations with multiscale data
beyond periodicity and scale separation. The authors
- provide a careful error analysis, including previously unpublished
results,
- present a complete implementation of the LOD method in MATLAB, and
- reveal how the LOD method relates to classical homogenization and
domain decomposition.

IHPCES 2021, the 11th workshop in the series of "Advances in
High-Performance Computational Earth Sciences" workshops,
will take place in conjunction with the ICCS 2021 Conference
in Krakow, Poland, from June 16-18, 2021.
https://www.cspp.cc.u-tokyo.ac.jp/IHPCES2021/
The objective of this series of workshops is to provide a forum for
presentation and discussion of state-of-the-art research in high
performance computational earth sciences. IHPCES workshops foster
communication between Earth scientists, applied mathematicians, and
computer scientists. The workshop therefore presents a unique
opportunity to exchange advanced knowledge, computational methods, and
science discoveries in computational geosciences. Specific topics of
interest include, but are not limited to: Large-scale simulations on
supercomputing systems in earth sciences; Advanced modeling and
simulations on natural disaster prevention and mitigation; Advanced
numerical methods for high performance computational earth sciences;
Parallel and distributed algorithms and programming strategies for
supercomputers; Software engineering for parallel systems with
multi-core processors and accelerators; Algorithms for Big Data
analytics and applications for large-scale data processing;
Methodologies and tools designed for extreme-scale computing.

Subject: PhD Position, Online Learning, Univ of Edinburgh
Funding, including fees + stipend, is available for UK or EU students
who want to pursue PhD studies in machine learning and randomised
algorithms for scientific computing. The focus of this project is to
look into portable, dimension independent computing that can
accommodate situations where resources are limited, e.g. edge
computing, federated learning or processing streaming data.
The position is suitable to candidates with a first degree and ideally
a Masters in applied mathematics or statistics including data science.
Knowledge of fundamental machine learning and linear algebra is a
plus. Enquiries can be made by email to [log in to unmask]

PhD position on "Control oriented analysis of linear periodic
delay-differential algebraic equations"
Delay-differential algebraic equations (DDAEs) naturally appear in
mathematical models for dynamical systems. A systematic description of
the components of the system and their interconnections leads to a
combination of differential equations and algebraic constraints, while
the delays model the inherent time-lags in the interconnections. The
analysis of systems described by DDAEs is challenging due to the
interplay between the implicit system description and the
infinite-dimensional dynamics
The project aims at the construction of an overarching mathematical
framework for the analysis of linear time-invariant and time-periodic
DDAEs. First, the basic theory will be addressed, contributing to
stability and Floquet theory, and to perturbation theory. Second,
analysis methods and computational tools will be constructed to assess
and optimize the robustness of the stationary solution. Distinct
features in the methodology are the role of duality, in a system
theoretic sense, and connections with nonlinear eigenvalue
problems. In order to reach the objectives, the theories of
differential equations, matrix distance problems, algebraic decision
problems, and robust control approaches will be integrated.
The ideal candidate has a MSc degree in mathematics (pure, applied,
computational), mathematical engineering, or control engineering (with
a strong interest in systems theory). We offer a fully funded PhD
position in an international context at the Numerical Analysis and
Applied Mathematics section of KU Leuven, a top university and hub for
interdisciplinary research in the fields of Applied Mathematics and
Systems & Control.
