摘要:

如果一个老师可以在精简iid训练集的同时让学习者学得更好,我们称之为超级可教的学习者。我们在两个学习器上提供了尖锐的超级教学保证:高斯均值的极大似然估计器和1D中的大间隔分类器。对于一般的学习器,我们提供了一个基于混合整数非线性规划的算法来找到一个超级教学集。实验结果表明,该算法能够为回归和分类问题找到良好的超教学集。

英文摘要:

We call a learner super-teachable if a teacher can trim down an iid training set while making the learner learn even better. We provide sharp super-teaching guarantees on two learners: the maximum likelihood estimator for the mean of a Gaussian, and the large margin classifier in 1D. For general learners, we provide a mixed-integer nonlinear programming-based algorithm to find a super teaching set. Empirical experiments show that our algorithm is able to find good super-teaching sets for both regression and classification problems.
