Towards the Interpretability of Deep Learning Models for Multi-Modal Neuroimaging: Finding Structural Changes of the Ageing Brain

Simon M. Hofmann, Klaus-Robert Müller, Wojciech Samek, Arno Villringer, Sebastian Lapuschkin, Frauke Beyer, Markus Loeffler, A. Veronica Witte, Ole Goltermann

Brain-age (BA) estimates based on deep learning are increasingly used as neuroimaging biomarker for brain health; however, the underlying neural features have remained unclear. We combined ensembles of convolutional neural networks with...

Selection of XAI Methods Matters: Evaluation of Feature Attribution Methods for Oculomotoric Biometric Identification

Daniel Krakowczyk, Sebastian Lapuschkin, David Robert Reich, Paul Prasse, Lena Ann Jäger, Tobias Scheffer

Substantial advances in oculomotoric biometric identification have been made due to deep neural networks processing non-aggregated time series data that replace methods processing theoretically motivated engineered features. In this work, we...

New Definitions of Human Lymphoid and Follicular Cell Entities in Lymphatic Tissue by Machine Learning

Patrick Wagner, Klaus-Robert Müller, Wojciech Samek, Frederick Klauschen, Arturo Marban, Nils Strodthoff, Philipp Seegerer, Patrick Wurzel, Sonja Scharf, Hendrik Schäfer, Andreas Loth, Sylvia Hartmann, Martin-Leo Hansmann

Histological sections of the lymphatic system are usually the basis of static (2D) morphological investigations. Here, we performed a dynamic (4D) analysis of human reactive lymphoid tissue using confocal fluorescent laser microscopy in...

Time Adaptive Probabilistic Shaping for Combined Optical/THz Links

In-Ho Baek, Colja Schubert, Ronald Freund, Robert Elschner, Frederik Bart, Fred Meier, David Hellmann, Andreas Maaßen

We investigate the applicability of PAS for outdoor THz wireless links in simulations with weather-dependent loss models. Link performances are evaluated and optimal shaping entropies are determined to adjust error rates to a given FEC threshold....

Towards Trustworthy AI in Dentistry

Jackie Ma, Wojciech Samek, Sebastian Lapuschkin, Falk Schwendicke, Joachim Krois, Lisa Schneider, Reduan Achtibat, Martha Duchrau

Medical and dental artificial intelligence (AI) require the trust of both users and recipients of the AI to enhance implementation, acceptability, reach, and maintenance. Standardization is one strategy to generate such trust, with quality...

Federated Learning in Dentistry: Chances and Challenges

Roman Rischke, Karsten Müller, Wojciech Samek, Falk Schwendicke, Joachim Krois, Lisa Schneider

Building performant and robust artificial intelligence (AI)–based applications for dentistry requires large and high-quality data sets. Collaborative efforts are limited as privacy constraints forbid direct sharing across the borders of these...
