The problem of semi-supervised induction consists in learning a decision rule from labeled and unlabeled data. 30 Entropy Regularization patterns. For metric learning, entropy regularization improves manifold regularization by considering the dissimilarity information of unlabeled data in the unsupervised part, and hence it allows the supervised and unsupervised parts to be integrated in a natural and meaningful way. 2012. Across the data sets XR outperforms na¨ıve Bayes, SVMs, EM, maximum entropy, entropy regularization (serving also as a stand-in for transductive SVMs), cluster kernels, as well as a graph-based method.

Tutorial on Semi-Supervised Learning Chicago 2009 14 / 99. Semi-supervised learning is halfway between unsupervised learning and supervised learning, i.e., there are both labeled and unlabeled data. 3 PDF View 1 excerpt, cites methods Examples of graph-based semi-supervised algorithms include label propagation [1], graph mincuts [2], ran- domized mincuts [3], and regularization on graphs [4,5]. As the data augmentation continued to ob-tain practical effects, the adjustment of hyperparameters and network structure became increasingly critical, con-sistency regularization that forces the predictive results to have consistency under various disturbances .
