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

1 code implementation • 5 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 implementation • 6 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.
