Toward efficient resource utilization at edge nodes in federated learning

no code implementations19 Sep 2023 Sadi Alawadi, Addi Ait-Mlouk, Salman Toor, Andreas Hellander

In this paper, we propose and evaluate a FL strategy inspired by transfer learning in order to reduce resource utilization on devices, as well as the load on the server and network in each global training round.

FedQAS: Privacy-aware machine reading comprehension with federated learning

1 code implementation9 Feb 2022 Addi Ait-Mlouk, Sadi Alawadi, Salman Toor, Andreas Hellander

In addition, we present the architecture and implementation of the system, as well as provide a reference evaluation based on the SQUAD dataset, to showcase how it overcomes data privacy issues and enables knowledge sharing between alliance members in a Federated learning setting.

Apache Spark Streaming and HarmonicIO: A Performance and Architecture Comparison

no code implementations20 Jul 2018 Ben Blamey, Andreas Hellander, Salman Toor

Studies have demonstrated that Apache Spark, Flink and related frameworks can perform stream processing at very high frequencies, whilst tending to focus on small messages with a computationally light `map' stage for each message; a common enterprise use case.

Orchestral: a lightweight framework for parallel simulations of cell-cell communication

2 code implementations28 Jun 2018 Adrien Coulier, Andreas Hellander

By the use of operator-splitting we decouple the simulation of reaction-diffusion kinetics inside the cells from the simulation of molecular cell-cell interactions occurring on the boundaries between cells.

Multi-Statistic Approximate Bayesian Computation with Multi-Armed Bandits

no code implementations22 May 2018 Prashant Singh, Andreas Hellander

This allows approximate Bayesian computation rejection sampling to dynamically focus on a distribution over well performing summary statistics as opposed to a fixed set of statistics.
