Second place in iDASH 2022 competition on secure record linkage

Our group consisting of Christoph Hofmeister, Maximilian Egger, Luis Maßny, and Afonso de Sá Delgado Neto ranks second in the renowned iDASH competition 2022, track 4: secure record linkage.
Every year, the Department of Biomedical Informatics at UCSD, the School of Biomedical Informatics at UTHealth, and the School of Informatics and Computing at Indiana University host the well-known privacy protection challenge called iDASH. The competition was initiated to investigate privacy and security concerns in cloud-based applications for critical medical data. This year, the teams could choose from four tasks, out of which one was about secure record linkage. Here, an algorithm should be designed that finds matching entries in the datasets of two parties while preserving the privacy of the parties' data.
We joined as team "COD" and placed second against a large number of competitors from academia and industry (http://www.humangenomeprivacy.org/2022/). The results were presented on the iDASH 2022 Genome Privacy and Security Workshop in November 2022. The recording of the talk, together with the slides, can be found at http://www.humangenomeprivacy.org/2022/agenda.html.

The TUM-Team formed by Christoph Hofmeister, Maximilian Egger, and Cengizhan Kaya gets awarded second place in the ITW competition 2022.
In Autumn 2022, the Information Theory Workshop (ITW) hosted the first ITW competition as part of the invited session on "Communication-efficient gradient compression and coding in distributed learning". The task was about training a channel state information (CSI) compressor for massive MIMO in 5G under severe communication constraints. In three subtasks, the competitors trained autoencoders in a federated fashion to cope with communication constraints and provide failure resilience in CSI compression.
The TUM team consisted of the master student Cengizhan Kaya and the doctoral researchers Christoph Hofmeister and Maximilian Egger at the Professorship of Coding and Cryptography and achieved second place (https://itw2022.in/themed-session-announcements/).
