WebHighlights. Query strategy, which selects the most anomalous samples, is a sub-optimal approach for deep one-class classification. We tackle two essential problems of active learning for deep SVDD; query strategy and semi-supervised learning method. We propose uncertainty sampling with an adaptive boundary without data-dependent hyper-parameters. WebJul 15, 2024 · We leverage recent advances in self-supervised representation learning followed by the cluster-based outlier detection to achieve competitive performance. This repository support both self-supervised training of networks and outlier detection evaluation of pre-trained networks.

Outlier detection, which is used to detect any outliers or data that largely varies in range from the normal operating range or state of the system within the training data. In this case, the complete data is analyzed to ... WebMar 28, 2024 · The most outlier point among the m = 1500 reported outliers has a rank of 1. In the same fashion, we develop Detector-5000 and Detector-7000 where m = 5000 and m = 7000 respectively. Our motivation for selecting so large m is that we want to feed the semi-supervised detector with the most confident normal data points.
