摘要:

主动学习是一种用于减少数据标记工作的机器学习方法。给定一个未标记的样本池,它试图选择最有用的样本进行标记,以便从它们构建的模型可以实现最佳性能。本文主要研究基于池的顺序主动学习回归算法(ALR)。我们首先提出了三个基本标准,ALR的方法应该考虑在选择最有用的未标记的样本:信息量,代表性和多样性,并比较现有的ALR方法对他们。然后,我们提出了一种新的ALR方法,使用被动采样,它既考虑了初始化和后续迭代的代表性和多样性。值得注意的是,这种方法也可以与文献中其他现有的ALR方法相结合,以进一步提高性能。在11个UCI,CMU StatLib和UFL Media Core数据集上进行了广泛的实验,验证了我们提出的ALR方法的有效性。

英文摘要:

Active learning is a machine learning approach for reducing the data labeling effort. Given a pool of unlabeled samples, it tries to select the most useful ones to label so that a model built from them can achieve the best possible performance. This paper focuses on pool-based sequential active learning for regression (ALR). We first propose three essential criteria that an ALR approach should consider in selecting the most useful unlabeled samples: informativeness, representativeness, and diversity, and compare four existing ALR approaches against them. We then propose a new ALR approach using passive sampling, which considers both the representativeness and the diversity in both the initialization and subsequent iterations. Remarkably, this approach can also be integrated with other existing ALR approaches in the literature to further improve the performance. Extensive experiments on 11 UCI, CMU StatLib, and UFL Media Core datasets from various domains verified the effectiveness of our proposed ALR approaches.
