  3. 2. Overcoming generative likelihood bias for voxel-based out-of-distribution detection

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Einar Lennelöv; [2021]
    Nyckelord :Variational autoencoder; out-of-distribution detection; likelihood bias; voxel representation; radiation therapy; Variationell autokodare; anomalidetektion; sannolikhetssnedvridning; voxelrepresentation; strålbehandling;

    Sammanfattning : Deep learning-based dose prediction is a promising approach to automated radiotherapy planning but carries with it the risk of failing silently when the inputs are highly abnormal compared to the training data. One way to address this issue is to develop a dedicated outlier detector capable of detecting anomalous patient geometries. LÄS MER

  4. 3. Fraud Detection on Unlabeled Data with Unsupervised Machine Learning

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Martin Renström; Timothy Holmsten; [2018]
    Nyckelord :Anomaly detection; fraud detection; unsupervised machine learning; autoencoder; Anomali detektering; bedrägeri detektering; oövervakad maskininlärning; autoencoder;

    Sammanfattning : A common problem in systems handling user interaction was the risk for fraudulent behaviour. As an example, in a system with credit card transactions it could have been a person using a another user's account for purchases, or in a system with advertisment it could be bots clicking on ads.
