Web02. nov 2024. · One-Class SVM (OC-SVM) is a common unsupervised approach to detect outliers. It considers all the data points as positively labeled instances and builds around them a smooth boundary to detect ‘strange’ samples. Recently, various approaches based on feature extraction models appear to be a valid instrument to use with OC-SVM. WebIn this thesis we study to what extent outlier-selection and one-class classification algorithms can support domain experts with real-world anomaly detection. The PDF can also be downloaded separately (228 pages, 10MB). Figures. The figures in the thesis are created using Python, MATLAB and TikZ.
