摘要翻译：
最先进的音频事件检测(AED)系统依赖于使用强标记数据的监督学习。然而，这种依赖性严重限制了大规模数据集的可伸缩性，在这些数据集中，获得精细分辨率注释的成本太高。在本文中，我们提出了一个使用弱标注标签的小占用空间多实例学习(MIL)框架，用于多类AED。提出的MIL框架使用从预先训练的卷积神经网络中提取的音频嵌入作为输入特征。我们表明，通过使用音频嵌入，MIL框架可以用一个简单的DNN来实现，其性能可以与递归神经网络相媲美。我们通过使用AudioSet的一个子集训练一个音频标记系统来评估我们的方法，AudioSet是一个大量弱标记的YouTube视频摘录的集合。结合后期融合方法，我们将基线音频标记系统的F1得分提高了17%。结果表明，卷积神经网络提取的音频嵌入显著提高了所有MIL模型的性能。该框架降低了AED系统的模型复杂度，适用于计算资源有限的应用。

英文摘要：
  State-of-the-art audio event detection (AED) systems rely on supervised learning using strongly labeled data. However, this dependence severely limits scalability to large-scale datasets where fine resolution annotations are too expensive to obtain. In this paper, we propose a small-footprint multiple instance learning (MIL) framework for multi-class AED using weakly annotated labels. The proposed MIL framework uses audio embeddings extracted from a pre-trained convolutional neural network as input features. We show that by using audio embeddings the MIL framework can be implemented using a simple DNN with performance comparable to recurrent neural networks.   We evaluate our approach by training an audio tagging system using a subset of AudioSet, which is a large collection of weakly labeled YouTube video excerpts. Combined with a late-fusion approach, we improve the F1 score of a baseline audio tagging system by 17%. We show that audio embeddings extracted by the convolutional neural networks significantly boost the performance of all MIL models. This framework reduces the model complexity of the AED system and is suitable for applications where computational resources are limited.
