Description: The package includes the MATLAB code of the SFL (Storage Fit Learning with unlabeled data) which focuses on the graph-based semi-supervised learning and includes two storage fit learning approaches NysCK and SoCK, which can adjust their behaviors to different storage budgets.[1]. You will find four main processes whose names include 'main' in which NysCK and SoCK are invoked seperately in two settings. The two example datasets are adult-a and australian which lie in './data/LargeScale/' and './data/RegularScale/' respectivly.
