Submissions for NA Digest:

From: Alexandre Ern
Date: May 25, 2021
Subject: New Book, Finite Elements

We are glad to announce the publication of the three volumes of our
monograph on finite elements:

Finite Elements, Texts in Applied Mathematics (TAM), Springer 2021
- I. Approximation and Interpolation (TAM volume 72)
- II. Galerkin Approximation, Elliptic and Mixed PDEs (TAM volume 73)
- III. First-Order and Time-Dependent PDEs (TAM volume 74)

Each volume is a textbook that is suitable for graduate coursework,
academic research, and professional engineering. One salient feature
of the monograph is the organization of the material into relatively
short chapters (12 to 14 pages on average). Each chapter can be
covered in one teaching unit and includes exercises. The organization
into short chapters will also be useful to experts looking for
references to the literature on some specialized topics. Altogether,
the three volumes are organized into 83 chapters and contain about 500
exercises. A fourth volume with the solutions to all the exercises is
available at

Subject: Computational Machine Learning Course, USA, Aug-Nov, 2021

Announcing enrollment for the Fall cohort of U. Michigan Online Course
on Computational Machine Learning for Scientists and Engineers.
Dates: August 11 - November 17, 2021
Enroll by: July 11, 2021

The Continuum Jumpstart Course Computational Machine Learning (ML) for
Scientists and Engineers is designed to equip you with the knowledge
you need to understand, train, and design machine learning algorithms,
particularly deep neural networks, and even deploy them on the cloud.
You'll learn by programming machine learning algorithms from scratch
in a hands-on manner using a one-of-a-kind cloud-based interactive
computational textbook that will guide you, and check your progress,
step-by-step. Using real-world datasets and datasets of your choosing,
you will understand, and we will discuss, via computational discovery
and critical reasoning, the strengths and limitations of the
algorithms and how they can or cannot be overcome. You will understand
how machine learning algorithms do what they claim to do so you can
reproduce these while being able to reason about and spot wild,
unsupported claims of their efficacy. By the end of the course, you
will be ready to harness the power of machine learning in your daily
job and prototype, we hope, innovative new ML applications for your
company with datasets you alone have access to.

nontrivial open-ended projects proposed by clients from industry or
academia. The course instructors mentor these teams in problem
solving, project management, team dynamics, leadership, technical
communication, and career skills.

Applicants must have a strong background in computational science or
data analytics, with demonstrated leadership solving interdisciplinary
problems in a business, government, or research setting; the ability
to teach students with diverse interests, backgrounds, and abilities
as they tackle open-ended, ambiguous problems; and
commitment/sensitivity to address issues of diversity in the
university community. Applicants must have earned a master's degree or
doctorate in Computer Science, Mathematics, Statistics, or a related
field at the time of appointment.
