RadPRISM: Schema-stratified radiology-report supervision for concept-disentangled image representations and visual grounding

Fabian Drexel, Marlene Fritzsche, Era Stambollxhiu +15

Vision-language pretraining learns rich medical image representations from radiology reports, but previous model variants commonly operate within a single shared embedding space, s…

Routine laboratory trajectories encode the onset of organ-level complications in cancer

Jannik Lübberstedt, Krischan Braitsch, Jacqueline Lammert +21

Routine laboratory panels drawn during cancer treatment constitute longitudinal physiological recordings of organ function, yet their temporal structure is discarded by single-time…

GRASP: Gated Regression-Aware Skill Proposer for Self-Improving LLM Agents

Johannes Moll, Jean-Philippe Corbeil, Jiazhen Pan +4

LLM agents acting in structured environments fail in operational rather than conversational ways, and reliability depends on procedural knowledge of the environment. Prior self-imp…

Evaluating Reasoning Faithfulness in Medical Vision-Language Models using Multimodal Perturbations

Johannes Moll, Markus Graf, Tristan Lemke +7

Vision-language models (VLMs) often produce chain-of-thought (CoT) explanations that sound plausible yet fail to reflect the underlying decision process, undermining trust in high-…
