基于卷积神经网络的多层时间池声场景分类

Acoustic scene classification using multi-layer temporal pooling based on convolutional neural network

Liwen Zhang, Jiqing Han

摘要:

声学场景分类系统的性能高度依赖于音频信号的潜在时间动态特性。本文提出了一种以CNN特征序列为输入的多层时域池方法,通过建立序列与其时间索引之间的直接联系,可以有效地捕获任意时长的整个音频信号的时域动态特性。我们将我们的新框架应用于DCASE 2018任务1,ASC。为了评估,我们训练了一个支持向量机(SVM)与建议多层时间池(MLTP)学习功能。在开发数据集上的实验结果表明,MLTP功能的使用显著提高了ASC的性能。通过使用我们实验中发现的最佳设置,实现了75.28%的准确率的最佳性能。

英文摘要:

The performance of an Acoustic Scene Classification (ASC) system is highly depending on the latent temporal dynamics of the audio signal. In this paper, we proposed a multiple layers temporal pooling method using CNN feature sequence as in-put, which can effectively capture the temporal dynamics for an entire audio signal with arbitrary duration by building direct connections between the sequence and its time indexes. We applied our novel framework on DCASE 2018 task 1, ASC. For evaluation, we trained a Support Vector Machine (SVM) with the proposed Multi-Layered Temporal Pooling (MLTP) learned features. Experimental results on the development dataset, usage of the MLTP features significantly improved the ASC performance. The best performance with 75.28% accuracy was achieved by using the optimal setting found in our experiments.
