At present, there is a lack of research on Marx's idea of "combining education and productive labor" and its guiding significance for youth labor education, and no effective teaching model has been formed. In response to this problem, this study proposes a semi-supervised deep learning model based on u-wordMixup (SD-uwM). When there is a shortage of labeled samples, semi-supervised learning uses a large number of unlabeled samples to solve the problem of labeling bottlenecks. However, since the unlabeled samples and labeled samples come from different fields, there may be quality problems in the unlabeled samples, which makes the generalization ability of the model worse., resulting in a decrease in classification accuracy. The model uses the u-wordMixup method to perform data augmentation on unlabeled samples. Under the constraints of supervised cross-entropy and unsupervised consistency loss, it can improve the quality of unlabeled samples and reduce overfitting. The comparative experimental results on the AGNews, THUCNews, and 20Newsgroups data sets show that the proposed method can improve the generalization ability of the model and also effectively improve the time performance. The study found that the SD-uwM model uses the u-wordMixup method to enhance the unlabeled samples and combines the idea of the Mean Teacher model, which can significantly improve the text classification performance. The SD-uwM model can improve the generalization ability and time performance of the model, respectively, 86.4 ± 1.3 and 90.5 ± 1.3. Therefore, the use of SD-uwM in Marx's program is of great practical significance for the guidance process of youth labor education.
目前,关于马克思“教育与生产劳动相结合”思想及其对青年劳动教育的指导意义的研究还比较缺乏,也没有形成有效的教学模式。针对这一问题,本研究提出了一种基于 u-wordMixup(SD-uwM)的半监督深度学习模型。当标记样本不足时,半监督学习利用大量未标记样本解决标记瓶颈问题。然而,由于未标记样本和标记样本来自不同的领域,未标记样本可能存在质量问题,这会使模型的泛化能力变差,从而导致分类精度下降。该模型使用 u-wordMixup 方法对未标记样本进行数据增强,在监督交叉熵和无监督一致性损失的约束下,可以提高未标记样本的质量,减少过拟合。在 AGNews、THUCNews 和 20Newsgroups 数据集上的对比实验结果表明,所提出的方法可以提高模型的泛化能力,同时有效提高时间性能。研究发现,SD-uwM 模型使用 u-wordMixup 方法增强未标记样本,并结合 Mean Teacher 模型的思想,可显著提高文本分类性能。SD-uwM 模型分别可以提高模型的泛化能力和时间性能,分别为 86.4±1.3 和 90.5±1.3。因此,在青年劳动教育的指导过程中,使用 SD-uwM 具有重要的现实意义。
