摘要翻译：
强标签的缺乏严重限制了最先进的全监督音频标签系统向更大的数据集扩展。同时，基于无标记视频的视听学习模型已经成功地应用于音频标注，但它们不可避免地存在资源匮乏和训练时间长的问题。在这项工作中，我们提出了一个轻量级的，多模态的环境音频标签框架。该框架的音频分支是基于多实例学习(MIL)的卷积递归神经网络(CRNN)。它是用大量弱标签YouTube视频摘录的音轨训练的；视频分支使用预先训练的最先进的图像识别网络和词嵌入来从视频轨道中提取信息，并将视觉对象映射到声音事件。在DCASE 2017挑战赛音频标记任务上的实验表明，视频信息的引入使强基线音频标记系统的绝对得分提高了5.3%$F_1$score。整个系统在单个GPU上可以在6~h内完成训练，并且可以很容易地进行语音情感分析等其他音频任务。

英文摘要：
The lack of strong labels has severely limited the state-of-the-art fully supervised audio tagging systems to be scaled to larger dataset. Meanwhile, audio-visual learning models based on unlabeled videos have been successfully applied to audio tagging, but they are inevitably resource hungry and require a long time to train. In this work, we propose a light-weight, multimodal framework for environmental audio tagging. The audio branch of the framework is a convolutional and recurrent neural network (CRNN) based on multiple instance learning (MIL). It is trained with the audio tracks of a large collection of weakly labeled YouTube video excerpts; the video branch uses pretrained state-of-the-art image recognition networks and word embeddings to extract information from the video track and to map visual objects to sound events. Experiments on the audio tagging task of the DCASE 2017 challenge show that the incorporation of video information improves a strong baseline audio tagging system by 5.3\% absolute in terms of $F_1$ score. The entire system can be trained within 6~hours on a single GPU, and can be easily carried over to other audio tasks such as speech sentimental analysis.
