Semi-supervised Sound Event Detection with Local and Global Consistency Regularization

no code implementations15 Sep 2023 Yiming Li, Xiangdong Wang, Hong Liu, Rui Tao, Long Yan, Kazushige Ouchi

Then, the local consistency is adopted to encourage the model to leverage local features for frame-level predictions, and the global consistency is applied to force features to align with global prototypes through a specially designed contrastive loss.

Audio-free Prompt Tuning for Language-Audio Models

no code implementations15 Sep 2023 Yiming Li, Xiangdong Wang, Hong Liu

Contrastive Language-Audio Pretraining (CLAP) is pre-trained to associate audio features with human language, making it a natural zero-shot classifier to recognize unseen sound categories.

Audio Generation with Multiple Conditional Diffusion Model

no code implementations23 Aug 2023 Zhifang Guo, Jianguo Mao, Rui Tao, Long Yan, Kazushige Ouchi, Hong Liu, Xiangdong Wang

To address this issue, we propose a novel model that enhances the controllability of existing pre-trained text-to-audio models by incorporating additional conditions including content (timestamp) and style (pitch contour and energy contour) as supplements to the text.

Sound Event Detection Transformer: An Event-based End-to-End Model for Sound Event Detection

1 code implementation5 Oct 2021 Zhirong Ye, Xiangdong Wang, Hong Liu, Yueliang Qian, Rui Tao, Long Yan, Kazushige Ouchi

A critical issue with the frame-based model is that it pursues the best frame-level prediction rather than the best event-level prediction.

Guided learning for weakly-labeled semi-supervised sound event detection

1 code implementation6 Jun 2019 Liwei Lin, Xiangdong Wang, Hong Liu, Yueliang Qian

Instead of designing a single model by considering a trade-off between the two sub-targets, we design a teacher model aiming at audio tagging to guide a student model aiming at boundary detection to learn using the unlabeled data.
