Power Pooling: An Adaptive Pooling Function for Weakly Labelled Sound Event Detection
July 18, 2021 By: Yuzhuo Liu, Hangting Chen, Yun Wang, Pengyuan Zhang Abstract Access to large corpora with strongly labelled sound events is expensive and difficult in engineering applications. Many researches turn to address the problem of how to detect both the types and the timestamps of sound events with weak labels that only specify the types. This task can be treated as a multiple instance learning (MIL) problem, and a key to it in the sound event detection (SED) […]
