摘要翻译:
本文提出了一种神经网络结构和训练方案来学习音频记录中声音事件(强标签)的开始和结束时间,只给出音频中存在的没有时间信息(弱标签)的声音事件列表。我们使用一个堆叠的卷积递归
神经网络来实现这一点,该网络具有两个预测层,一个预测层是强的,然后是弱的。该网络的训练使用帧内对数Mel频带能量作为输入音频特征,数据集中提供的弱标签作为弱标签预测层的标签。强标签是通过复制弱标签与输入音频特征中的帧一样多的次数来生成的,并在训练时用于强标签层。我们建议通过对两个预测层计算的损失进行不同的加权来控制网络从弱标签和强标签中学习的内容。该方法在一个155小时的公开数据集上进行了评估,该数据集包含17个声音事件类。该方法对强标签的最佳错误率为0.84,对弱标签的最佳F分值为43.3%。

英文摘要:
This paper proposes a neural network architecture and training scheme to learn the start and end time of sound events (strong labels) in an audio recording given just the list of sound events existing in the audio without time information (weak labels). We achieve this by using a stacked convolutional and recurrent neural network with two prediction layers in sequence one for the strong followed by the weak label. The network is trained using frame-wise log mel-band energy as the input audio feature, and weak labels provided in the dataset as labels for the weak label prediction layer. Strong labels are generated by replicating the weak labels as many number of times as the frames in the input audio feature, and used for strong label layer during training. We propose to control what the network learns from the weak and strong labels by different weighting for the loss computed in the two prediction layers. The proposed method is evaluated on a publicly available dataset of 155 hours with 17 sound event classes. The method achieves the best error rate of 0.84 for strong labels and F-score of 43.3% for weak labels on the unseen test split.
