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.

Towards Human-Interpretable Prototypes for Visual Assessment of Image Classification Models

no code implementations22 Nov 2022 Poulami Sinhamahapatra, Lena Heidemann, Maureen Monnet, Karsten Roscher

Explaining black-box Artificial Intelligence (AI) models is a cornerstone for trustworthy AI and a prerequisite for its use in safety critical applications such that AI models can reliably assist humans in critical decisions.

Is it all a cluster game? -- Exploring Out-of-Distribution Detection based on Clustering in the Embedding Space

no code implementations16 Mar 2022 Poulami Sinhamahapatra, Rajat Koner, Karsten Roscher, Stephan Günnemann

It is essential for safety-critical applications of deep neural networks to determine when new inputs are significantly different from the training distribution.

OODformer: Out-Of-Distribution Detection Transformer

1 code implementation19 Jul 2021 Rajat Koner, Poulami Sinhamahapatra, Karsten Roscher, Stephan Günnemann, Volker Tresp

A serious problem in image classification is that a trained model might perform well for input data that originates from the same distribution as the data available for model training, but performs much worse for out-of-distribution (OOD) samples.

Scenes and Surroundings: Scene Graph Generation using Relation Transformer

1 code implementation12 Jul 2021 Rajat Koner, Poulami Sinhamahapatra, Volker Tresp

Identifying objects in an image and their mutual relationships as a scene graph leads to a deep understanding of image content.
