Power pooling: An adaptive pooling function for weakly labelled sound event detection
Yuzhuo Liu, Hangting Chen, YunWang +1
Access to large corpora with strongly labelled sound events is expensive and difficult in engineering applications. Much research turns to address the problem of how to detect both…
Power Pooling Operators and Confidence Learning for Semi-Supervised Sound Event Detection
Yuzhuo Liu, Hangting Chen, Pengyuan Zhang
In recent years, the involvement of synthetic strongly labeled data,weakly labeled data and unlabeled data has drawn much research attentionin semi-supervised sound event detection…
Multi-Talker MVDR Beamforming Based on Extended Complex Gaussian Mixture Model
Hangting Chen, Pengyuan Zhang, Yonghong Yan
In this letter, we present a novel multi-talker minimum variance distortionless response (MVDR) beamforming as the front-end of an automatic speech recognition (ASR) system in a di…
Integrating the Data Augmentation Scheme with Various Classifiers for Acoustic Scene Modeling
Hangting Chen, Zuozhen Liu, Zongming Liu +2
This technical report describes the IOA team's submission for TASK1A of DCASE2019 challenge. Our acoustic scene classification (ASC) system adopts a data augmentation scheme employ…
