Upcoming Talk at WFLP 2018

Our paper “Functional Federated Learning in Erlang (ffl-erl)” has been accepted for presentation at The 26th International Workshop on Functional and Logic Programming (WFLP 2018), which is held at the University of Frankfurt, Frankfurt am Main, Germany, on 6 September 2018. The abstract is reproduced below.

Functional Federated Learning in Erlang (ffl-erl)
Gregor Ulm, Emil Gustavsson and Mats Jirstrand

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 decentralized 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.
