New dual-encoder model fuses waveform and spectrograms for acoustic classification

Researchers have developed a novel dual-encoder neural network architecture designed to improve underwater acoustic classification. This model simultaneously processes both raw acoustic waveforms and spectrograms, utilizing parameter-efficient fine-tuning for domain adaptation. A key innovation is the integration of a differentiable Choquet integral for fusing these representations, which enhances classification accuracy and offers interpretability by revealing reliance on temporal versus spectral data. Evaluations on benchmark datasets show improved performance over single-encoder methods while reducing the number of trainable parameters. AI
