Semi-Supervised Sound Event Detection with Conditional Mixup and Embedding-Level Contrastive Loss

Nian Shao, Xian Li, Xiaofei Li

Sound event detection (SED) is a core module for acoustic environmental analysis, yet its performance is often limited by scarce labeled data. Recent systems leverage large pretrained audio foundation models, but effective fine-tuning remains challenging because labeled data are…Read more
