      Polyps are well-known cancer precursors identified by colonoscopy. However, variability in their size, appearance, and location makes the detection of polyps challenging. Moreover, colonoscopy surveillance and removal of polyps are highly operator-dependent procedures and occur in a highly complex organ topology. There exists a high missed detection rate and incomplete removal of colonic polyps. To ...
    • Between Memory and History. Retracing Historical Knowledge through a Phenomenology of Afterlife 

      Anden, Anna Lovisa (Chapter; Bokkapittel, 2023-12-13)
      How can Jan Patočka’s phenomenology of afterlife enable us to understand the historiographical process in general and the role of testimony in the historiographical process, in particular? Patočka presents a phenomenological analysis of co-existence and afterlife where others continue to be with us, as a part of our lifeworld and our constitution of ourselves, even after they are gone. We see ourselves ...
    • PSAIR: A Neuro-Symbolic Approach to Zero-Shot Visual Grounding 

      Pan, Yi; Zhang, Yujia; Kampffmeyer, Michael Christian; Zhao, Xiaoguang (Chapter; Bokkapittel, 2024-09-09)
      Supervised methods for Visual Grounding often require costly annotations of paired sentences and images with ground truth boxes. Recent zero-shot approaches to visual grounding such as ReCLIP and ChatRef aim to avoid the need for costly annotation of paired sentences and images with ground truth boxes. However, these approaches leverage an inflexible detect-then-reasoning paradigm, which leads to a ...
