  1. 1. Non-Bayesian Out-of-Distribution Detection Applied to CNN Architectures for Human Activity Recognition

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Serghei Socolovschi; [2022]
    Keywords : Human Activity Recognition; Deep Learning; Time Series; Uncertainty Estimation; Outofdistribution Detection; Convolutional Neural Network; Human Activity Recognition; Deep Learning; Tidsserie; Uppskattning av Osäkerheten; Outofdistribution Detection; Convolutional Neural Network;

    Abstract : Human Activity Recognition (HAR) field studies the application of artificial intelligence methods for the identification of activities performed by people. Many applications of HAR in healthcare and sports require the safety-critical performance of the predictive models. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  3. 3. Evaluating Unsupervised Methods for Out-of-Distribution Detection on Semantically Similar Image Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Magnus Pierrau; [2021]
    Keywords : Out-of-distribution detection; anomaly detection; semantic similarity; image data; comparative evaluation; synthetic image data; Out-of-distribution detektion; anomali detektion; semantisk likhet; bilddata; jämförande utvärdering; syntetisk bilddata;

    Abstract : Out-of-distribution detection considers methods used to detect data that deviates from the underlying data distribution used to train some machine learning model. This is an important topic, as artificial neural networks have previously been shown to be capable of producing arbitrarily confident predictions, even for anomalous samples that deviate from the training distribution.

  4. 4. Impact of Semantic Segmentation on OOD Detection Performance for VAEs and Normalizing Flow Models

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Norrman; [2021]
    Keywords : ;

    Abstract :  To achieve a higher grade of reliability among deep learning models, OOD (Out-Of-Distribution) detection has become an increasingly more prominent research field. What OOD detection does is to make the model figure out if inputted data is data it is meant to be trained on, or if it is data from a new distribution, giving the model a sense of its own ignorance.

  5. 5. Detecting Synthetic Images of Faces using Deep Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johan Sabel; [2020]
    Keywords : ;

    Abstract : Significant progress has been made within human face synthesis due to recent advances in generative adversarial networks. These networks can be used to generate credible high-quality images of faces not belonging to real people, which is something that could be exploited by malicious actors. READ MORE
