Adaptive DCTNet for audio signal classification

Yin Xian, Yunchen Pu, Zhe Gan, Liang Lu, Andrew Thompson

ICASSP 2017accepted

In this paper, we investigate DCTNet for audio signal classification. Its output feature is related to Cohen's class of time-frequency distributions. We introduce the use of adaptive DCTNet (A-DCTNet) for audio signals feature extraction. The A-DCTNet applies the idea of constant-Q transform, with i…

Classification of whale vocalizations using the Weyl transform

Yin Xian, Andrew Thompson, Qiang Qiu, Loren W. Nolte, Douglas Nowacek, Jianfeng Lu +1

ICASSP 2015accepted

In this paper, we apply the Weyl transform to represent the vocalization of marine mammals. In contrast to other popular representation methods, such as the MFCC and the Chirplet transform, the Weyl transform captures the global information of signals. This is especially useful when the signal has l…
