Abstract

In deep learning, it is necessary to train on huge datasets to obtain accurate models, but in certain domains, such as medical imaging, it is difficult to develop large datasets. Therefore, research is being conducted to realize good accuracy, even with small datasets. One strategy to achieve good accuracy with small datasets is input data augmentation. However, input data augmentation needs to be carefully prepared according to the domain. In this article, we propose an interlayer augmentation method that produces new data between layers. Then, we propose batch generalization (BG) and random BG (RBG) as specific methods. We applied BG and RBG to VGG, ResNet, and ViT, evaluated each using CIFAR10 and CIFAR100 classification tasks, and compared them with scratch learning. We obtained an average improvement of 0.39% and 0.27% for RBG and BG, respectively, in CIFAR10 and an average improvement of 1.07% and 0.30% for RBG and BG, respectively, in CIFAR100. In particular, in all cases, RBG showed better results than scratch learning.
分类任务中的层间增强
在深度学习中,需要在庞大的数据集上进行训练以获得准确的模型,但在某些领域,如医学成像,很难开发大型数据集。因此,研究正在进行,以实现良好的准确性,即使是在小数据集。在小数据集上实现良好精度的一种策略是输入数据增强。但是,需要根据领域仔细准备输入数据增强。在本文中,我们提出了一种层间增强方法,在层间产生新的数据。然后,我们提出了批量泛化(BG)和随机BG (RBG)作为具体方法。我们将BG和RBG应用于VGG、ResNet和ViT,使用CIFAR10和CIFAR100分类任务对它们进行评估,并将它们与scratch学习进行比较。我们在CIFAR10中RBG和BG的平均改善分别为0.39%和0.27%,在CIFAR100中RBG和BG的平均改善分别为1.07%和0.30%。特别是,在所有情况下,RBG表现出比从头学习更好的结果。
