Öğe SSS-Net: A shadowed-sets-based semi-supervised sample selection network for classification on noise labeled images(Elsevier, 2023) Cai, Kecan; Zhang, Hongyun; Pedrycz, Witold; Miao, DuoqianSample selection is a fundamental technique utilized in image classification with noisy labels. A plethora of sample selection approaches published in the literature are based on a small-loss strategy, in which division thresholds are set manually and the correlation between sample losses is ignored. Furthermore, one of the most evident shortcomings of these approaches is that noisy samples with low-quality pseudo-labels can negatively impact the model resulting in poor performance. In this study, a shadowed-sets-based semi-supervised sample selection network called SSS-Net is developed to address these limitations. Our approach leverages a novel technique that combines a loss-similarity-based-clustering method (LSCM) with the shadowed-sets theory to adaptively select clean samples. We then introduce an original high-quality pseudo-label sample reselection (HPSR) strategy, which is designed through the co-training of two networks, to pick the samples with high-quality pseudo-labels. Finally, the selected samples are utilized to further train the network and complete classification. This study presents an automated approach that determines optimal division thresholds to select clean samples adaptively. Furthermore, it improves the current semi-supervised sample selection method by effectively utilizing noisy samples. The suitability and promising performance of the proposed approach are supported through experimental studies using five real-world datasets. Comparative studies involving several state-of-the-art methods are also reported. & COPY; 2023 Elsevier B.V.

Different from the recent learning machines, the proposed learning machine takes the feature-oriented information, label-oriented information, and associated information between features and labels in multiple representations together and exploits the hidden useful information of available instances with the usage of instance-instance correlations, feature-feature correlations, label-label correlations, and feature-label correlations. The developed learning machine is named as within- cross-consensus view representation-based multi-view multi-label learning with incomplete data (WCC-MVML-ID). Extensive experiments on multiple multi-view and multi-label data sets with incomplete data validate the effectiveness of WCC-MVML-ID and it can be concluded that (1) WCC-MVML-ID outperforms other compared learning machines and its performances are more stable even though the missing rates of features and labels being larger; (2) compared with within-view information and consensus-view information, cross-view information is more useful for the processing problem about incomplete data; (3) WCC-MVML-ID can converge within 45 iterations.
