  1. 6. Detecting Images Outside Training Distribution for Fingerprint Spoof Detection

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Daniel Holmkvist; [2023]
    Nyckelord :Machine learning; Out-of-Distribution; Deep Neural Network; spoof detection; Neural Network; Mathematics and Statistics;

    Sammanfattning : Artificial neural networks are known to run into issues when given samples that deviate from the training distribution, where the network may confidently provide an incorrect answer. Out-of-distribution detection methods aims to provide a solution to this issue, by detecting data that deviates from the distribution used to train the model. LÄS MER
