      <p>Melanoma Classification - a 10,000$ competition. For the 2020 Melanoma Classification competition hosted by kaggle, 33,126 images were made available for training (of which 2% were melanomas), and an additional 10,982 were used for final ranking of the 3,308 teams who entered the competition with eyes on the 10,000$ prize. The task was simple: provide a probability for melanoma (deadly skin cancer) ...
    • The blind leading the blind? Filling the knowledge gap by student peer assessment 

      Møllersen, Kajsa (Conference object; Konferansebidrag, 2023-03)
      Prior knowledge in certain mathematical topics is essential for fundamental understanding of most STEM subjects, and closing the gap from secondary education is a prerequisite for success. The teacher's dilemma in higher education is the time dedicated to teaching secondary level maths versus the course's actual curriculum. To close the knowledge gap for a group of PhD students at the Faculty of ...
    • Cancer detection for white urban Americans 

      Møllersen, Kajsa; Bongo, Lars Ailo; Tafavvoghi, Masoud (Conference object; Konferansebidrag, 2023-06)
      Development, validation and comparison of machine learning methods require access to data, sometimes lots of data. Within health applications, data sharing can be restricted due to patient privacy, and the few publicly available data sets become even more valuable for the machine learning community. One such type of data are H&E whole slide images (WSI), which are stained tumour tissue, used in ...
    • Changes in maternal risk factors and their association with changes in cesarean sections in Norway between 1999 and 2016: A descriptive population-based registry study 

      Nedberg, Ingvild Hersoug; Lazzerini, Marzia; Mariani, Ilaria; Møllersen, Kajsa; Valente, Emanuelle Pessa; Anda, Erik Eik; Skjeldestad, Finn Egil (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-03)
      Background - Increases in the proportion of the population with increased likelihood of cesarean section (CS) have been postulated as a driving force behind the rise in CS rates worldwide. The aim of the study was to assess if changes in selected maternal risk factors for CS are associated with changes in CS births from 1999 to 2016 in Norway.<p> <p>Methods and findings - This national ...
    • Comparison of computer systems and ranking criteria for automatic melanoma detection in dermoscopic images 

      Møllersen, Kajsa; Zortea, Maciel; Schopf, Thomas Roger Griesbeck; Kirchesch, Herbert M.; Godtliebsen, Fred (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-21)
      Melanoma is the deadliest form of skin cancer, and early detection is crucial for patient survival. Computer systems can assist in melanoma detection, but are not widespread in clinical practice. In 2016, an open challenge in classification of dermoscopic images of skin lesions was announced. A training set of 900 images with corresponding class labels and semi-automatic/manual segmentation masks ...
    • Integrative, multi-omics, analysis of blood samples improves model predictions: applications to cancer 

      Ponzi, Erica; Thoresen, Magne; Haugdahl Nøst, Therese; Møllersen, Kajsa (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-05)
      <i>Background</i> - Cancer genomic studies often include data collected from several omics platforms. Each omics data source contributes to the understanding of the underlying biological process via source specific (“individual”) patterns of variability. At the same time, statistical associations and potential interactions among the different data sources can reveal signals from common biological ...

      <p>The old “Lofoten Post” building sits at the end of the dock in Svolvær as an empty shell, ready for the winter storms to seal its destiny. Everything that reminds of newspaper production is stripped from the building, only dents from the editor’s desk can still be seen on the floor. Wait! A stack of newspapers, filled with tables of fishery, trade, crimes, and everything else that transforms small ...

    • A Probabilistic Bag-to-Class Approach to Multiple-Instance Learning 

      Møllersen, Kajsa; Hardeberg, Jon Yngve; Godtliebsen, Fred (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-26)
      Multi-instance (MI) learning is a branch of machine learning, where each object (bag) consists of multiple feature vectors (instances)—for example, an image consisting of multiple patches and their corresponding feature vectors. In MI classification, each bag in the training set has a class label, but the instances are unlabeled. The instances are most commonly regarded as a set of points in a ...
    • Surgeon’s experience and clinical outcome after retropubic tension‐free vaginal tape - A case series 

      Holdø, Bjørn; Møllersen, Kajsa; Verelst, Margareta; Milsom, Ian; Svenningsen, Rune; Skjeldestad, Finn Egil (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-27)
      <i>Introduction</i> - The retropubic tension‐free vaginal tape procedure has been the preferred method for primary surgical treatment of stress and stress‐dominant mixed urinary incontinence in women for more than 20 years. In this study, we assessed associations between surgeon's experience with the primary tension‐free vaginal tape procedure and both perioperative complications and recurrence ...
