Additional data for "Trajectory Variance: An Unsupervised Measure of Developmental Vocal Plasticity in Birdsong"

Trained variational autoencoder (VAE) checkpoints and per-vocalization latent representations for three developing zebra finches (183K–274K vocalizations each, 40–101 days post-hatch), accompanying the Interspeech 2026 paper "Trajectory Variance: An Unsupervised Measure of Developmental Vocal Plasticity in Birdsong." With the code at https://github.com/hwiora/trajectory_variance, these files reproduce the paper's evaluation tables. The raw audio recordings are not included; they are available from the authors on request and will be released in a future study. See ZENODO_README.md for details.
