  3. 7. Truncation and missing family links in population-based registers

    Författare :Monica Leu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Left-trunction; Swedish Cancer Registry; MultiGeneration Register; family history; misclassification; simulation; Poplab;

    Sammanfattning : Studies of familial aggregation of disease routinely use linked population registers to construct retrospective cohorts. Although such resources have provided numerous estimates of familial risk, little is known regarding the sensitivity of the estimates to assumed disease models and incompleteness of the data, such as truncation and/or missing family links.

  4. 8. Generalization under Model Mismatch and Distributed Learning

    Författare :Martin Hellkvist; Ayca Özcelikkale; Anders Ahlén; Martin Jaggi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Signal processing; Generalization error; Training error; Double-descent; Double descent; Distributed learning; Distributed optimization; Learning over networks; Model mismatch; Model misspecification; Fake features; Missing features; linear regression; regularization; Machine learning; Maskininlärning;

    Sammanfattning : Machine learning models are typically configured by minimizing the training error over a given training dataset. On the other hand, the main objective is to obtain models that can generalize, i.e., perform well on data unseen during training. LÄS MER

  5. 9. Fear and missing out : internet-treatment for social anxiety disorder in youth

    Författare :Martina Nordh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Social anxiety disorder (SAD) is common, highly impairing and associated with severe effects on functioning and with increased monetary costs for the society. The disorder typically emerges during childhood and tends to follow a persistent and chronic course if left untreated. LÄS MER

  7. 10. Additively Manufactured Inconel 718 : Microstructures and Mechanical Properties

    Författare :Dunyong Deng; Johan Moverare; Ru Lin Peng; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.
