An Asynchronous Approximate Distributed Alternating Direction Method of Multipliers in Digraphs
Wei Jiang, Andreas Grammenos, Evangelia Kalyvianaki +1
In this work, we consider the asynchronous distributed optimization problem in which each node has its own convex cost function and can communicate directly only with its neighbors…
Optimal CPU Scheduling in Data Centers via a Finite-Time Distributed Quantized Coordination Mechanism
Apostolos I. Rikos, Andreas Grammenos, Evangelia Kalyvianaki +3
In this paper we analyze the problem of optimal task scheduling for data centers. Given the available resources and tasks, we propose a fast distributed iterative algorithm which o…
The INTERSPEECH 2021 Computational Paralinguistics Challenge: COVID-19 Cough, COVID-19 Speech, Escalation & Primates
Björn W. Schuller, Anton Batliner, Christian Bergler +21
The INTERSPEECH 2021 Computational Paralinguistics Challenge addresses four different problems for the first time in a research competition under well-defined conditions: In the CO…
Exploring Automatic Diagnosis of COVID-19 from Crowdsourced Respiratory Sound Data
Chloë Brown, Jagmohan Chauhan, Andreas Grammenos +6
Audio signals generated by the human body (e.g., sighs, breathing, heart, digestion, vibration sounds) have routinely been used by clinicians as indicators to diagnose disease or a…
Federated Principal Component Analysis
Andreas Grammenos, Rodrigo Mendoza-Smith, Jon Crowcroft +1
We present a federated, asynchronous, and -differentially private algorithm for PCA in the memory-limited setting. Our algorithm incrementally computes local mode…
MOSES: A Streaming Algorithm for Linear Dimensionality Reduction
Armin Eftekhari, Raphael A. Hauser, Andreas Grammenos
This paper introduces Memory-limited Online Subspace Estimation Scheme (MOSES) for both estimating the principal components of streaming data and reducing its dimension. More speci…
