摘要翻译：
近十年来，音频标签技术引起了越来越多的关注，并在许多领域有着潜在的应用前景。音频标签的目标是预测音频片段的标签。近年来，深度学习方法被应用于音频标注，并取得了较高的性能，但对新数据的泛化能力较差。然而，由于音频标签数据（如DCASE数据）的大小有限，训练后的模型往往导致网络的过拟合。以往的数据增强方法，如基音移动、时间拉伸和添加背景噪声等，在音频标记方面并没有显示出太大的改善。本文针对国内音频标注任务，探讨了样本混合数据的增强方法，包括混合、采样和外推。我们应用一个具有注意力模块的卷积递归神经网络(CRNN)作为基线系统，该神经网络具有对数标度的mel谱。在我们的实验中，我们在DCASE 2016 task4数据集上使用混合方法获得了0.10的等误码率(EER)，优于没有数据增强的基线系统。

英文摘要：
Audio tagging has attracted increasing attention since last decade and has various potential applications in many fields. The objective of audio tagging is to predict the labels of an audio clip. Recently deep learning methods have been applied to audio tagging and have achieved state-of-the-art performance, which provides a poor generalization ability on new data. However due to the limited size of audio tagging data such as DCASE data, the trained models tend to result in overfitting of the network. Previous data augmentation methods such as pitch shifting, time stretching and adding background noise do not show much improvement in audio tagging. In this paper, we explore the sample mixed data augmentation for the domestic audio tagging task, including mixup, SamplePairing and extrapolation. We apply a convolutional recurrent neural network (CRNN) with attention module with log-scaled mel spectrum as a baseline system. In our experiments, we achieve an state-of-the-art of equal error rate (EER) of 0.10 on DCASE 2016 task4 dataset with mixup approach, outperforming the baseline system without data augmentation.
