3. 2. Self-supervised representation learning from electrocardiogram data for medical applications

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Matilda Andersson; [2023]
   Nyckelord :Self-supervised learning; Deep learning; Cardiovascular disease; Electrocardiogram; ECG; SimCLR; BYOL; VICReg; Mathematics and Statistics;

   Sammanfattning : Cardiovascular diseases are the leading cause of death worldwide, increasing yearly. However, many abnormalities in heart cycles can be discovered and treated years before the onset of diseases. But in most societies, regular health checkups are a concept reserved for cars, not humans. LÄS MER

4. 3. Anomaly detection in surveillance camera data
