GRASP: Guided Residual Adapters with Sample-wise Partitioning

Felix Nützel, Mischa Dombrowski, Bernhard Kainz

Text-to-image flow matching transformers degrade sharply in long-tail settings: tail-class outputs collapse in fidelity and diversity, limiting their value as synthetic augmentatio…

Generate to Ground: Multimodal Text Conditioning Boosts Phrase Grounding in Medical Vision-Language Models

Felix Nützel, Mischa Dombrowski, Bernhard Kainz

Phrase grounding, i.e., mapping natural language phrases to specific image regions, holds significant potential for disease localization in medical imaging through clinical reports…
