摘要翻译：
本文提出了一种从音频流中早期检测音频事件的方法。早期发现是在事件的初始阶段推断正在发生的事件的能力。该系统由一个新的推理步骤与双并行定制损失深度神经网络（DNNs）耦合组成。除了损失函数（加权损失和多任务损失）之外，DNN共享类似的结构，这些损失函数旨在有效地解决音频事件检测中常见的问题。新引入了推理步骤，利用网络输出来识别正在进行的事件。检测函数的单调性是可靠的早期检测所需要的，也将得到证明。在ITC-Irst数据库上的实验表明，该系统达到了最先进的检测性能。此外，即使是部分事件也足以实现与观察到整个事件时所获得的良好性能相似的良好性能，从而实现早期事件检测。

英文摘要：
  This paper presents a methodology for early detection of audio events from audio streams. Early detection is the ability to infer an ongoing event during its initial stage. The proposed system consists of a novel inference step coupled with dual parallel tailored-loss deep neural networks (DNNs). The DNNs share a similar architecture except for their loss functions, i.e. weighted loss and multitask loss, which are designed to efficiently cope with issues common to audio event detection. The inference step is newly introduced to make use of the network outputs for recognizing ongoing events. The monotonicity of the detection function is required for reliable early detection, and will also be proved. Experiments on the ITC-Irst database show that the proposed system achieves state-of-the-art detection performance. Furthermore, even partial events are sufficient to achieve good performance similar to that obtained when an entire event is observed, enabling early event detection.
