使用原型网络和数据增强的生物声学事件检测

Bioacoustic Event Detection with prototypical networks and data augmentation

Mark Anderson, Naomi Harte

摘要:

本报告介绍了进入DCASE 2021挑战赛的Few-Shot生物声学事件检测的系统所使用的深度学习和数据增强技术。任务是为动物(哺乳动物和鸟类)发声开发一个Few-Shot学习系统。参与者的任务是开发一种方法,可以从哺乳动物或鸟类的五个范例发声或镜头中提取信息,并在现场录音中检测和分类声音。在本报告中描述的系统中,原型网络用于学习度量空间,通过计算查询点到类原型的距离来执行分类,基于最短距离进行分类。我们描述了这个网络的架构,特征提取方法和对给定数据集执行的数据增强,并将我们的工作与挑战的基线网络进行比较。

英文摘要:

This report presents deep learning and data augmentation techniques used by a system entered into the Few-Shot Bioacoustic Event Detection for the DCASE2021 Challenge. The remit was to develop a few-shot learning system for animal (mammal and bird) vocalisations. Participants were tasked with developing a method that can extract information from five exemplar vocalisations, or shots, of mammals or birds and detect and classify sounds in field recordings. In the system described in this report, prototypical networks are used to learn a metric space, from which classification is performed by computing the distance of a query point to class prototypes, classifying based on shortest distance. We describe the architecture of this network, feature extraction methods, and data augmentation performed on the given dataset and compare our work to the challenge's baseline networks.
