What Do Neural Networks Learn for TDOA Estimation? A Cross-Architecture Probing Study
Yaozhong Kang, Jiang Wang, Runwu Shi +3
Neural networks outperform classical GCC-PHAT for Time-Difference-of-Arrival (TDOA) estimation in noise and reverberation, yet their internal strategy remains unexplored. To uncove…

Fast-SDE: Efficient Single-Microphone Sound Source Distance Estimation in Reverberant Environments
Jiang Wang, Runwu Shi, Yaozhong Kang +3
Sound source distance estimation (SDE) is a critical capability in human-robot interaction. An inappropriate interaction distance not only reduces the reliability of speech acquisi…

Ecologically-Constrained Task Arithmetic for Multi-Taxa Bioacoustic Classifiers Without Shared Data
Ragib Amin Nihal, Benjamin Yen, Runwu Shi +2
Training data for bioacoustics is scattered across taxa, regions, and institutions. Centralizing it all is often infeasible. We show that independently fine-tuned BEATs encoders ca…
