Contrastive Loss Based Frame-Wise Feature Disentanglement for Polyphonic Sound Event Detection

ICASSP 2024accepted

Overlapping sound events are ubiquitous in real-world environments, but existing end-to-end sound event detection (SED) methods still struggle to detect them effectively. A critical reason is that these methods represent overlapping events using shared and entangled frame-wise features, which degrad…

Modeling Quasi-Periodic Dependency via Self-Supervised Pre-Training for Respiratory Sound Classification

ICASSP 2024accepted

Despite the success of self-supervised respiratory sound classification methods, they do not consider that respiratory sounds are quasi-periodic signals with repetitive patterns in successive breaths, which is vital for distinguishing respiratory sounds from non-quasi-periodic sounds like noises. Th…

Sentiment Knowledge Enhanced Self-supervised Learning for Multimodal Sentiment Analysis

ACL 2023findings

Multimodal Sentiment Analysis (MSA) has made great progress that benefits from extraordinary fusion scheme. However, there is a lack of labeled data, resulting in severe overfitting and poor generalization for supervised models applied in this field. In this paper, we propose Sentiment Knowledge Enh…

Deep Neural Network Based Discriminative Training for I-Vector/PLDA Speaker Verification

ICASSP 2018accepted

In the studies of i-vector based speaker verification, the discriminative training of probabilistic linear discriminative analysis (PLDA) model has been proven to be an effective way to improve performance. This paper focuses on using a deep neural network (DNN) to strengthen the original discrimina…
