Corpus Considerations for Annotator Modeling and Scaling

1 code implementation2 Apr 2024 Olufunke O. Sarumi, Béla Neuendorf, Joan Plepi, Lucie Flek, Jörg Schlötterer, Charles Welch

We introduce a composite embedding approach and show distinct differences in which model performs best as a function of the agreement with a given dataset.

Prototype-based Interpretable Breast Cancer Prediction Models: Analysis and Challenges

1 code implementation29 Mar 2024 Shreyasi Pathak, Jörg Schlötterer, Jeroen Veltman, Jeroen Geerdink, Maurice van Keulen, Christin Seifert

Specifically, we apply three state-of-the-art prototype-based models, ProtoPNet, BRAIxProtoPNet++ and PIP-Net on mammography images for breast cancer prediction and evaluate these models w. r. t.

PIPNet3D: Interpretable Detection of Alzheimer in MRI Scans

no code implementations27 Mar 2024 Lisa Anita De Santi, Jörg Schlötterer, Michael Scheschenja, Joel Wessendorf, Meike Nauta, Vincenzo Positano, Christin Seifert

Information from neuroimaging examinations (CT, MRI) is increasingly used to support diagnoses of dementia, e. g., Alzheimer's disease.

A Second Look on BASS -- Boosting Abstractive Summarization with Unified Semantic Graphs -- A Replication Study

no code implementations5 Mar 2024 Osman Alperen Koraş, Jörg Schlötterer, Christin Seifert

We present a detailed replication study of the BASS framework, an abstractive summarization system based on the notion of Unified Semantic Graphs.

The Queen of England is not England's Queen: On the Lack of Factual Coherency in PLMs

1 code implementation2 Feb 2024 Paul Youssef, Jörg Schlötterer, Christin Seifert

In this work, we consider a complementary aspect, namely the coherency of factual knowledge in PLMs, i. e., how often can PLMs predict the subject entity given its initial prediction of the object entity.

Give Me the Facts! A Survey on Factual Knowledge Probing in Pre-trained Language Models

no code implementations25 Oct 2023 Paul Youssef, Osman Alperen Koraş, Meijie Li, Jörg Schlötterer, Christin Seifert

Our contributions are: (1) We propose a categorization scheme for factual probing methods that is based on how their inputs, outputs and the probed PLMs are adapted; (2) We provide an overview of the datasets used for factual probing; (3) We synthesize insights about knowledge retention and prompt optimization in PLMs, analyze obstacles to adopting PLMs as knowledge bases and outline directions for future work.

Weakly Supervised Learning for Breast Cancer Prediction on Mammograms in Realistic Settings

1 code implementation19 Oct 2023 Shreyasi Pathak, Jörg Schlötterer, Jeroen Geerdink, Onno Dirk Vijlbrief, Maurice van Keulen, Christin Seifert

We show that two-level MIL can be applied in realistic clinical settings where only case labels, and a variable number of images per patient are available.

Is Last Layer Re-Training Truly Sufficient for Robustness to Spurious Correlations?

no code implementations1 Aug 2023 Phuong Quynh Le, Jörg Schlötterer, Christin Seifert

Models trained with empirical risk minimization (ERM) are known to learn to rely on spurious features, i. e., their prediction is based on undesired auxiliary features which are strongly correlated with class labels but lack causal reasoning.

Guidance in Radiology Report Summarization: An Empirical Evaluation and Error Analysis

1 code implementation24 Jul 2023 Jan Trienes, Paul Youssef, Jörg Schlötterer, Christin Seifert

Automatically summarizing radiology reports into a concise impression can reduce the manual burden of clinicians and improve the consistency of reporting.

Interpreting and Correcting Medical Image Classification with PIP-Net

1 code implementation19 Jul 2023 Meike Nauta, Johannes H. Hegeman, Jeroen Geerdink, Jörg Schlötterer, Maurice van Keulen, Christin Seifert

We conclude that part-prototype models are promising for medical applications due to their interpretability and potential for advanced model debugging.

PIP-Net: Patch-Based Intuitive Prototypes for Interpretable Image Classification

1 code implementation CVPR 2023 Meike Nauta, Jörg Schlötterer, Maurice van Keulen, Christin Seifert

Driven by the principle of explainability-by-design, we introduce PIP-Net (Patch-based Intuitive Prototypes Network): an interpretable image classification model that learns prototypical parts in a self-supervised fashion which correlate better with human vision.

Explaining Machine Learning Models in Natural Conversations: Towards a Conversational XAI Agent

no code implementations6 Sep 2022 Van Bach Nguyen, Jörg Schlötterer, Christin Seifert

In this work, we show how to incorporate XAI in a conversational agent, using a standard design for the agent comprising natural language understanding and generation components.

Competitive Influence Maximization: Integrating Budget Allocation and Seed Selection

1 code implementation27 Dec 2019 Amirhossein Ansari, Masoud Dadgar, Ali Hamzeh, Jörg Schlötterer, Michael Granitzer

In this work, we integrate these two lines of research and propose a new scenario where competition happens in two phases.

Parallel Total Variation Distance Estimation with Neural Networks for Merging Over-Clusterings

no code implementations9 Dec 2019 Christian Reiser, Jörg Schlötterer, Michael Granitzer

We consider the initial situation where a dataset has been over-partitioned into $k$ clusters and seek a domain independent way to merge those initial clusters.

Policy Learning for Malaria Control

2 code implementations20 Oct 2019 Van Bach Nguyen, Belaid Mohamed Karim, Bao Long Vu, Jörg Schlötterer, Michael Granitzer

In this report, we introduce the progress to learn the policy for Malaria Control as a Reinforcement Learning problem in the KDD Cup Challenge 2019 and propose diverse solutions to deal with the limited observations problem.
