摘要
The system determines a version space associated with a set of data comprising a pool of unlabeled samples and a first plurality of labeled samples, wherein the version space includes a first set of classifiers corresponding to the first plurality of labeled samples. The system selects, from the pool of unlabeled samples, a second plurality of unlabeled samples comprising informative samples and non-informative samples. A respective informative sample corresponds to a first hyperplane which intersects the version space, and a respective non-informative sample corresponds to a second hyperplane which does not intersect the version space. The system acquires labels corresponding to the second plurality of unlabeled samples to obtain a third plurality of labeled samples. The system updates the first set of classifiers based on the third plurality of labeled samples, thereby improving accuracy of the first set of classifiers.
