基于凝聚信息瓶颈的音频事件聚类方法
Audio Events Clustering Based on Agglomerative Information Bottleneck
摘要
Abstract
In order to further improve the performance of methods for audio events clustering,this paper proposes a method for audio events clustering based on the theory of agglomerative information bottleneck.First,the principles and derivations of information bottleneck are briefly introduced.Then,the proposed method is described in detail,including the definitions of source variables,relevance variables and destination variables,the steps of the proposed method and the analyses of main computational loads of all methods.The proposed method and two kinds of previous methods (including the method based on spectral clustering,and the method based on both Bayesian information criterion and agglomerative hierarchical clustering) are evaluated on the experimental data extracted from two different corpora of audio events.The experimental results show that the proposed method obtains higher K values (geometric mean of average clustering purity and average audio purity) and runs faster than the previous methods under several experimental conditions.关键词
