Activities of the Data Mining Group at ECML/PKDD 2019

The Data Mining Group actively participated in a number of activities at the ECML/PKDD 2019 conference.

The group members presented research papers, posters and also organized two workshops. The workshop programs are available at the following links.

  • DeCoDeML (Deep Continuous-Discrete Machine Learning)
  • AIMLAI & XKDD (Advances in Interpretable Machine Learning and Artificial Intelligence & eXplainable Knowledge Discovery in Data mining)

The research paper "Pairwise Learning to Rank by Neural Networks Revisited: Reconstruction, Theoretical Analysis and Practical Performance: Marius Köppel*, Alexander Segner*, Martin Wagener*, Lukas Pensel*, Andreas Karwath^, Stefan Kramer*" was presented at the Ranking session.

The following papers were presented at the DeCoDeML and SoGood workshops.

DeCoDeML Spotlight Talk 1: Zahra Ahmadi, Sina Malakouti and Stefan Kramer. Deep Tree Networks: A New Symbolic Deep Architecture

DeCoDeML Spotlight Talk 3: Sophie Burkhardt, Nicolas Wagner, Johannes Fürnkranz and Stefan Kramer. Extracting Rules with Adaptable Complexity from Neural Networks using K-Term DNF Optimization

DeCoDeML Spotlight Talk 4: Nicolas Wagner, Sophie Burkhardt, Stefan Kramer. A Deep Convolutional DNF Learner

SoGood Talk: Lukas Pensel and Stefan Kramer. Forecast of Study Success in the STEM Disciplines Based Solely on Academic Record

The DeCoDeML workshop was organized for the first time and participation was well beyond the expectations of the organizing committee.

Talk by Prof. Dr. Anke Meyer-Baese

With the increasing amount of available medical data, computing power and network speed, modern medical
imaging is facing an unprecedented amount of data to analyze and interpret. Phenomena such as Big Data-omics stemming from several diagnostic procedures and novel multi-parametric imaging modalities tend to produce almost unmanageable quantities of data. The paper addresses the aforementioned context by assuming that a novel paradigm in massive data processing and automation becomes necessary in order to improve diagnostics and facilitate personalized and precision medicine for each patient. Traditional machine learning concepts have demonstrated many shortcomings when it comes to correctly diagnose fatal diseases. At the same time static graph networks are unable to capture the fluctuations in brain processing and monitor disease evolution. Therefore, artificial intelligence and deep learning are increasingly applied in oncologic medical imaging because they excel at providing quantitative assessments of biomedical imaging characteristics. On the other hand, novel concepts borrowed from modern control have paved the path for a dynamic graph theory that can predict neurodegenerative disease evolution and replace longitudinal studies. We chose two important topics, brain data processing and oncologic imaging to show the relevance of these concepts. We believe that these novel paradigms will impact multiple facets of radiology but are convinced that it is unlikely that they will replace radiologists any time in the near future since there are still many challenges in the clinical implementation.
