Abstract

En 中文

• TCA-Net integrates complementary time- and frequency-domain representations. • SNR-aware stochastic masking improves feature learning under severe noise. • Cross-band interaction strengthens low- and high-frequency representations. • TCA-Net outperforms five AMR baselines across three public datasets.
