摘要翻译：
当事件的时间边界可用于训练时，我们提出了一个简单的递归模型来检测罕见的声音事件。我们的模型优化了话语级损失和帧级损失的组合，前者分类事件是否发生在话语中，后者分类每个帧是否与事件发生时对应。这两个损失利用事件的共享矢量表示，并通过注意机制连接起来。我们在DCASE 2017挑战赛的任务2上展示了我们的模型，并取得了竞争性的表现。

英文摘要：
  We propose a simple recurrent model for detecting rare sound events, when the time boundaries of events are available for training. Our model optimizes the combination of an utterance-level loss, which classifies whether an event occurs in an utterance, and a frame-level loss, which classifies whether each frame corresponds to the event when it does occur. The two losses make use of a shared vectorial representation the event, and are connected by an attention mechanism. We demonstrate our model on Task 2 of the DCASE 2017 challenge, and achieve competitive performance.
