Finding Dino: A plug-and-play framework for unsupervised detection of out-of-distribution objects using prototypes

no code implementations11 Apr 2024 Poulami Sinhamahapatra, Franziska Schwaiger, Shirsha Bose, Huiyu Wang, Karsten Roscher, Stephan Guennemann

It is an inference-based method that does not require training on the domain dataset and relies on extracting relevant features from self-supervised pre-trained models.

Enhancing Interpretability of Vertebrae Fracture Grading using Human-interpretable Prototypes

no code implementations3 Apr 2024 Poulami Sinhamahapatra, Suprosanna Shit, Anjany Sekuboyina, Malek Husseini, David Schinz, Nicolas Lenhart, Joern Menze, Jan Kirschke, Karsten Roscher, Stephan Guennemann

In this work, we propose a novel interpretable-by-design method, ProtoVerse, to find relevant sub-parts of vertebral fractures (prototypes) that reliably explain the model's decision in a human-understandable way.

Efficient Bi-Directional Verification of ReLU Networks via Quadratic Programming

no code implementations25 Sep 2019 Aleksei Kuvshinov, Stephan Guennemann

Solving the single initial QP already results in a lower bound on the DtDB and can be used as a robustness certificate of the classifier around a given sample.

GhostLink: Latent Network Inference for Influence-aware Recommendation

no code implementations15 May 2019 Subhabrata Mukherjee, Stephan Guennemann

As additional use-cases, we show that GhostLink can be used to differentiate between users' latent preferences and influenced ones, as well as to detect influential users based on the learned influence graph.
