Topic: Functional Federated Learning in Erlang (ffl-erl)

The functional programming language Erlang is well-suited for
concurrent and distributed applications. Numerical computing, however,
is not seen as one of its strengths. The recent introduction of
Federated Learning, a concept according to which client devices are
leveraged for de-centralized machine learning tasks, while a central
server updates and distributes a global model, provided the motivation
for exploring how well Erlang is suited to that problem. We present
ffl-erl, a framework for Federated Learning, written in Erlang, and
explore how well it performs in two scenarios: one in which the entire
system has been written in Erlang, and another in which Erlang is
relegated to coordinating client processes that rely on performing
numerical computations in the programming language C. There is a
concurrent as well as a distributed implementation of each case.
Erlang incurs a performance penalty, but for certain use cases this
may not be detrimental, considering the trade-off between conciseness
of the language and speed of development (Erlang) versus performance
(C). Thus, Erlang may be a viable alternative to C for some practical
machine learning tasks.

Internship (Web Development) at the Fraunhofer-Chalmers Centre for Industrial Mathematics

Leave a reply

The Systems and Data Analysis department at the Fraunhofer-Chalmers Centre for Industrial Mathematics intends to hire a student for an internship. You would be working under my supervision and contribute to the development of a platform for distributed data analytics by creating a web-based interface. The goal of this internship is to create a more intuitive alternative to the existing command-line interface.

Here is the job ad:

Internship (Web Development) at the Fraunhofer-Chalmers Centre for Industrial Mathematics

The Fraunhofer-Chalmers Research Centre for Industrial Mathematics (FCC)
offers software, services and contract research for a broad range of
industrial applications. Modelling, simulation and optimization of products
and processes can boost technical development, improve efficiency and cut
costs of both large and small businesses. Since 2001, our highly skilled team
of mathematicians and engineers has successfully solved problems for more than
170 clients. We combine consultancy services with innovative research and
development based on a wide spectrum of competences.

We are looking for an ambitious student with a background in computer science
or related fields to assist in an ongoing applied research project in the
Systems and Data Analysis department.

Your task:
We have been developing a prototype for distributed data analytics. Currently,
the end user interacts with it via a Python library that is accessed through
a terminal window. In order to improve usability, we would like to add a HTML5-
based front-end to this system.

Required background:
- Experience with HTML5 and JavaScript
- Understanding of concurrency and asynchronous execution

Meriting:
- Experience with Python
- Awareness of Erlang

Your ideal profile:
- Chalmers student at the Master's level, preferably in the penultimate year
- Pursue a degree in Computer Science or a similar field
- Able to work independently
- Previous work experience in the software industry or as a student research
assistant

If you maintain a private code repository (Github, Gitlab, Bitbucket etc.),
then please highlight this in your application. If you have other samples of
work to show, such as a portfolio of projects on a blog or private website,
we would be keen to have a look.

This internship is a paid part-time (4h/week) fixed-term position until the
end of December 2018, with the possibility of extending the contract. The
starting date is flexible.

Please send your application, marked "Contracted Student / SYS (OODIDA
Front-End)", consisting of a cover letter, CV, and a current academic
transcript covering your entire university education, to
[email protected].

Interviews will be held continually. Please apply as soon as possible.
