Benchmarking nearest neighbor retrieval of zebra finch vocalizations across development

This study benchmarks nearest neighbor retrieval for zebra finch vocalizations, finding high performance in adults but lower in juveniles, with improved results using fixed-size templates and Spearman distance.

Extracting extended vocal units from two neighborhoods in the embedding plane

The paper introduces a semi-supervised method to segment and cluster vocalizations by identifying two density-based regions in low-dimensional embeddings, achieving lower false positive error rates.

Multimodal system for recording individual-level behaviors in songbird groups

The paper introduces a modular system for recording individual-level behaviors in songbird groups using multimodal sensors and custom software to improve signal integration and behavior detection.
