Collaborative Distributed Machine Learning

no code implementations28 Sep 2023 David Jin, Niclas Kannengießer, Sascha Rank, Ali Sunyaev

Various collaborative distributed machine learning (CDML) systems, including federated learning systems and swarm learning systems, with different key traits were developed to leverage resources for development and use of machine learning (ML) models in a confidentiality-preserving way.

How Automated Market Makers Approach the Thin Market Problem in Cryptoeconomic Systems

no code implementations22 Sep 2023 Daniel Kirste, Niclas Kannengießer, Ricky Lamberty, Ali Sunyaev

The proper design of automated market makers (AMMs) is crucial to enable the continuous trading of assets represented as digital tokens on markets of cryptoeconomic systems.

Scalable Data Point Valuation in Decentralized Learning

1 code implementation1 May 2023 Konstantin D. Pandl, Chun-Yin Huang, Ivan Beschastnikh, Xiaoxiao Li, Scott Thiebes, Ali Sunyaev

The valuation of data points through DDVal allows to also draw hierarchical conclusions on the contribution of institutions, and we empirically show that the accuracy of DDVal in estimating institutional contributions is higher than existing Shapley value approximation methods for federated learning.

Reward Systems for Trustworthy Medical Federated Learning

1 code implementation1 May 2022 Konstantin D. Pandl, Florian Leiser, Scott Thiebes, Ali Sunyaev

Especially bias, defined as a disparity in the model's predictive performance across different subgroups, may cause unfairness against specific subgroups, which is an undesired phenomenon for trustworthy ML models.

Practitioner Motives to Select Hyperparameter Optimization Methods

no code implementations3 Mar 2022 Niklas Hasebrook, Felix Morsbach, Niclas Kannengießer, Marc Zöller, Jörg Franke, Marius Lindauer, Frank Hutter, Ali Sunyaev

Advanced programmatic hyperparameter optimization (HPO) methods, such as Bayesian optimization, have high sample efficiency in reproducibly finding optimal hyperparameter values of machine learning (ML) models.

Architecture Matters: Investigating the Influence of Differential Privacy on Neural Network Design

1 code implementation29 Nov 2021 Felix Morsbach, Tobias Dehling, Ali Sunyaev

One barrier to more widespread adoption of differentially private neural networks is the entailed accuracy loss.

On the Convergence of Artificial Intelligence and Distributed Ledger Technology: A Scoping Review and Future Research Agenda

no code implementations29 Jan 2020 Konstantin D. Pandl, Scott Thiebes, Manuel Schmidt-Kraepelin, Ali Sunyaev

Previous work highlights several potential benefits of the convergence of AI and DLT but only provides a limited theoretical framework to describe upcoming real-world integration cases of both technologies.
