Noriyuki Tonami, Keisuke Imoto

TL;DR
This paper introduces sound event triage (SET), a flexible sound event detection task that prioritizes certain classes and allows adjustable detection emphasis, outperforming conventional methods on urban sound datasets.
Contribution
It proposes the novel task of SET with class-weighted training to prioritize sound classes, enabling adjustable detection focus, and demonstrates its effectiveness with experimental results.
Findings
SET outperforms conventional SED in key sound classes.
Class-weighted training improves detection of high-priority sounds.
Single target SET achieves significant F-score improvements.
Abstract
We propose a new task for sound event detection (SED): sound event triage (SET). The goal of SET is to detect an arbitrary number of high-priority event classes while allowing misdetections of low-priority event classes where the priority is given for each event class. In conventional methods of SED for targeting a specific sound event class, it is only possible to give priority to a single event class. Moreover, the level of priority is not adjustable, i.e, the conventional methods can use only types of target event class such as one-hot vector, as inputs. To flexibly control much information on the target event, the proposed SET exploits not only types of target sound but also the extent to which each target sound is detected with priority. To implement the detection of events with priority, we propose class-weighted training, in which loss functions and the network are stochastically…
