SALSA-Lite: A Fast and Effective Feature for Polyphonic Sound Event Localization and Detection with Microphone Arrays
Thi Ngoc Tho Nguyen, Douglas L. Jones, Karn N. Watcharasupat +2
Polyphonic sound event localization and detection (SELD) has many practical applications in acoustic sensing and monitoring. However, the development of real-time SELD has been lim…
SALSA: Spatial Cue-Augmented Log-Spectrogram Features for Polyphonic Sound Event Localization and Detection
Thi Ngoc Tho Nguyen, Karn N. Watcharasupat, Ngoc Khanh Nguyen +2
Sound event localization and detection (SELD) consists of two subtasks, which are sound event detection and direction-of-arrival estimation. While sound event detection mainly reli…
Improving Polyphonic Sound Event Detection on Multichannel Recordings with the Sørensen-Dice Coefficient Loss and Transfer Learning
Karn N. Watcharasupat, Thi Ngoc Tho Nguyen, Ngoc Khanh Nguyen +3
The Sørensen--Dice Coefficient has recently seen rising popularity as a loss function (also known as Dice loss) due to its robustness in tasks where the number of negative samples…
