Unlabeled Echoes: Pseudo-Labels and Genus-Aware Smoothing for Bat Call Recognition

Passive acoustic monitoring produces far more bat recordings than experts can label. We show that simple model-generated pseudo-labels turn this surplus into effective supervision. We compare pseudo-labeling with other semi-supervised learning methods on an 18-species European corpus using only 10% of its training labe...

What Moves? Localized Motion Representations for Compositional Scene Control

This work introduces a promptable localized motion representation that produces persistent embeddings for user-specified regions defined by spatial masks that improves controllability and outperforms global representations localized through cropping or post-hoc masking.
