The FeatureCloud Platform for Federated Learning in Biomedicine: Unified Approach
No full textBackground Machine learning and artificial intelligence have shown promising results in many areas and are driven by the increasing amount of available data. However, these data are often distributed across different institutions and cannot be easily shared owing to strict privacy regulations. Federated learning (FL) allows the training of distributed machine learning models without sharing sensitive data. In addition, the implementation is time-consuming and requires advanced programming skills and complex technical infrastructures. Objective Various tools and frameworks have been developed to simplify the development of FL algorithms and provide the necessary technical infrastructure. Although there are many high-quality frameworks, most focus only on a single application case or method. To our knowledge, there are no generic frameworks, meaning that the existing solutions are restricted to a particular type of algorithm or application field. Furthermore, most of these frameworks provide an application programming interface that needs programming knowledge. There is no collection of ready-to-use FL algorithms that are extendable and allow users (eg, researchers) without programming knowledge to apply FL. A central FL platform for both FL algorithm developers and users does not exist. This study aimed to address this gap and make FL available to everyone by developing FeatureCloud, an all-in-one platform for FL in biomedicine and beyond. Methods The FeatureCloud platform consists of 3 main components: a global frontend, a global backend, and a local controller. Our platform uses a Docker to separate the local acting components of the platform from the sensitive data systems. We evaluated our platform using 4 different algorithms on 5 data sets for both accuracy and runtime. Results FeatureCloud removes the complexity of distributed systems for developers and end users by providing a comprehensive platform for executing multi-institutional FL analyses and implementing FL algorithms. Through its integrated artificial intelligence store, federated algorithms can easily be published and reused by the community. To secure sensitive raw data, FeatureCloud supports privacy-enhancing technologies to secure the shared local models and assures high standards in data privacy to comply with the strict General Data Protection Regulation. Our evaluation shows that applications developed in FeatureCloud can produce highly similar results compared with centralized approaches and scale well for an increasing number of participating sites. Conclusions FeatureCloud provides a ready-to-use platform that integrates the development and execution of FL algorithms while reducing the complexity to a minimum and removing the hurdles of federated infrastructure. Thus, we believe that it has the potential to greatly increase the accessibility of privacy-preserving and distributed data analyses in biomedicine and beyond

Abstract
This thesis aims to study Niklas Luhmann’s theory of social systems and its educational implications. The first chapter explores major problems and predicament in the study of education. It also points out contributions of Luhmann to educational studies. The second chapter traces sources of Luhmann’s theory of intellectual traditions. The third chapter then explicates the structure of Luhmann’s theory with an analysis of important ideas and concepts implicated in his works.These ideas and concepts include , for example , system , complexity , meaning , function , communication , self-reference and others. The fourth chapter discusses how Luhmann has reflected on current educational systems on the basis of his own theory. In particular,Chapter Five takes up Luhmann’s discussion in Reflexionsprobleme im Erziehungssystem. The last chapter , in conclusion , reviews major themes of this research , identifies the difficulties thus encountered, and suggests possible directions for future studies.

Schlussbericht
No full textDas Projekt FeMAI zielte darauf ab, Methoden des föderierten maschinellen Lernens für die Analyse mikrobieller Daten zu entwickeln und in einer sicheren, datenschutzkonformen Umgebung bereitzustellen. Die Entstehung von kolorektalen Karzinomen (CRC) wird neben Faktoren wie Ernährung, Lebensstil und Komorbiditäten auch von einem dysbiotischen Darm-Mikrobiom beeinflusst (Dong and Gupta 2019). Durch die Quantifizierung dieses Mikrobioms lassen sich Aussagen über die Entstehung und Progression von CRC treffen (Zwezerijnen-Jiwa et al. 2023). Technisch wurde auf etablierten Analyseverfahren für Sequenzdaten, auf Ontologien für medizinische Datenintegration sowie auf föderierten Lernansätzen aufgebaut, die im Rahmen des FeatureCloud-Systems (Matschinske et al. 2021) bereits grundgelegt waren. Diese bestehenden Werkzeuge und Standards wurden erweitert, kombiniert und für den speziellen Anwendungsfall der Mikrobiomforschung

Briefe aus der Verbannung / Tristia. Epistulae ex Ponto : Lateinisch - Deutsch /
No full textIm Jahre 8 n. Chr. wird Ovid aus nicht bekanntem Grund von Kaiser Augustus nach Tomis am Schwarzen Meer verbannt, an den Rand der zivilisierten Welt, in eine trostlose Gegend, in der niemand Latein spricht und die er bis zu seinem Tod 17 n. Chr. nicht mehr verlassen wird. Er beginnt, verzweifelte Briefe zu schreiben - man würde sie heute "Offene Briefe" nennen - und diese nach Rom zur Veröffentlichung zu schicken. Sie sind sorgsam dichterisch komponiert, der Stil ist geschliffen und sie haben nur ein Ziel: die öffentliche Meinung in Rom für ihn einzunehmen; erfolglos, wie wir wissen. Gleichwohl sind die Briefe bewegende Dokumente frühester Exil-Literatur. Sie wurden das ganze Mittelalter über gelesen und haben das moderne Bewusstsein Europas mitgeprägt. Die neue Einführung des Münchner Altphilologen Niklas Holzberg und die neuen besonders ausführlichen Anmerkungen zu den unzähligen versteckten Anspielungen in den Briefen untersuchen sorgfältig, was an Ovids Klagen echt und was "Literatur" ist, wo er unter der Unerträglichkeit des Exils tatsächlich leidet und wo er nur gängigen Vorstellungen über die Wildnis am Pontos Ausdruck verleiht.

Scandal on campus. Dietrich Schwanitz reads Niklas Luhmann’s systems theory
No full textNiklas Luhmann (1927–1998) is one of the most distinguished sociologists of the twentieth cen-tury and the author of systems theory, which to a great extent has been accommodated into lin-guistics. Dietrich Schwanitz (1940–2004), an anglicist, is one of the most interesting interpreters of Luhmann on the basis of literary studies. Schwanitz is also known as a writer and author of the novel Campus (Der Campus, 1995). The main character, a sociologist, Hanno Hackmann, is wrongly accused of the sexual harassment and rape of a student. His reckless romance is exploited by various people in the university milieu to achieve their own goals. In fact, these people are, however, only the representatives of various social systems, especially politics and the media. Striving for re-election, the university rector needs this matter for his campaign, and the media are only interested in a scandalous story to be exploited for some time. Social communication does not reflect reality, and, at the same time, can be described as based on the “reduction of complexi-ty” (“Komplexitätsreduktion”). This is one of the most important concepts in Niklas Luhmann’s work. It turns out that systems theory provides the specific key to interpret the novel

Cross-Topic Author Identification -- a Case Study on Swedish Literature
No full textUsing material from the Swedish Literature Bank, we investigate whether common methods of author identification using word frequencies and part of speech frequencies are sensitive to differences in topic. The results show that this is the case, thereby casting doubt on much previous work in author identification. This sets the stage for a broader future study, comparing other methods and generalising the results

Niklas Luhmann, Crisis y Renovación en la Teoría Social del Siglo XX
No full textThe purpose of this article is to give a brief introduction to Luhmann's thought, focusing on the changes of the 20th century positions and analyzing basic concepts of the author. Likewise, to review that Niklas Luhmann's social theory adopts a new way of understanding a society that has become more complex in the stage of modernity/postmodernity, in which for the author, the classical theory does not have the explanatory elements for such phenomena. Luhmann's theory is closely linked to the epistemological changes of the second half of the 20th century and the advances in science and technology.El presente artículo tiene como objetivo dar una breve introducción al pensamiento de Luhmann, enfocándose en los cambios de las posturas del siglo XX y analizando conceptos básicos del autor. Así misml, revisar que la teoría social de Niklas Luhmann adopta una nueva forma de comprender a una sociedad que se ha complejizado en la etapa de la modernidad/posmodernidad, en la cual para el autor, la teoría clásica no tiene los elementos explicativos para dichos fenómenos. La teoría de Luhmann está muy ligada a los cambios epistemológicos de la segunda mitad del siglo XX y los avances en las ciencias, tecnología
