当前,深度主动学习(Deep Active Learning,DAL)在分类数据标注工作中获得成功,但如何筛选出最能提升模型性能的样本仍是难题.本文提出基于弱标签争议的半自动分类数据标注方法(Dispute about Weak Label based Deep Active Learning,DWLDAL),迭代地筛选出模型难以区分的样本,交给人工进行准确标注.该方法包含伪标签生成器和弱标签生成器,伪标签生成器是在准确标注的数据集上训练而成,用于生成无标签数据的伪标签;弱标签生成器则是在带伪标签的随机子集上训练而成.弱标签生成器委员会决定哪些无标签数据最有争议,则交给人工标注.本文针对文本分类问题,在公开数据集IMDB(Internet Movie DataBase)、20NEWS(20NEWSgroup)和chnsenticorp(chnsenticorp_htl_all)上进行实验验证.从数据标注和分类任务的准确性2个角度,对3种不同投票决策方式进行评估.DWLDAL方法中数据标注的

At present
deep active learning (DAL) in the classification data labeling work has achieved outstanding success. How to select samples to improve the performance of models is still a difficult problem in deep active learning. We proposes a semi-automatic classification data labeling method based on weak label dispute (Dispute about Weak Label-based Deep Active Learning
DWLDAL). The method iteratively selects samples that is difficult for model to distinguish
and manually annotate these sample. This method contains pseudo label generator and weak label generator
pseudo label generator is trained on accurately annotated datasets to generate pseudo label for unlabeled data; weak label generator is trained on random data subset with pseudo labels. Weak label generator committee are used to determine which unlabeled data is the most controversial and should be manually annotated. We conducted experimental validation on the common datasets IMDB (Internet Movie Database)
20NEWS (20NEWSgroup)
and chnsenticorp (chnsenticorp_htl_all) to address the issue of text classification. Three different voting decision-making methods are evaluated from the perspective of the accuracy of data annotation and classification tasks. The

score of data annotation in DWLDAL method is 30.22%
14.07% and 2.57% higher than that in the existing method Snuba
respectively. The
F

score of classification task in DWLDAL method is 1.01%
22.72% and 4.83% higher than that in Snuba method
respectively.
