Interactive Weak Supervision for Transferring Sound Libraries to Passive Acoustic Monitoring

Passive Acoustic Monitoring (PAM) enables continuous and non-invasive biodiversity monitoring, but analysing large acoustic datasets remains difficult because sound event detectors usually require temporally precise annotations. Creating such instance-level labels is expensive and requires expert knowledge. At the same time, museum and community-run sound libraries provide large numbers of animal Read more

Grounded Label Space Engineering for Knowledge-Centric Annotation Workflows

Building reliable AI models depends not only on how much data is annotated, but on the quality and meaning of the labels used during annotation. In many workflows, labels are flat, task-specific class names. They are easy to apply, but lack explicit semantic structure, provenance, and links to shared domain Read more
