摘要:

主动学习策略通过在训练预测模型时选择最有用的未标记样本来响应监督分类中代价高昂的标记任务。许多传统的主动学习算法专注于细化决策边界,而不是探索可以提供更多信息的新区域。在这种情况下,我们提出了一个顺序算法EG-Active,可以提高任何主动学习算法的最佳随机探索。实验结果表明,我们的新方法在现有的主动反馈方法的性能在统计上显着和可观的改善。

英文摘要:

Active learning strategies respond to the costly labelling task in a supervised classification by selecting the most useful unlabelled examples in training a predictive model. Many conventional active learning algorithms focus on refining the decision boundary, rather than exploring new regions that can be more informative. In this setting, we propose a sequential algorithm named EG-Active that can improve any Active learning algorithm by an optimal random exploration. Experimental results show a statistically significant and appreciable improvement in the performance of our new approach over the existing active feedback methods.
