AFA-Net: A Differential Attention Approach for Auditory Attention Detection

Read the original on arXiv Machine Learning →

AFA‑Net introduces a differential attention mechanism to improve Auditory Attention Detection (AAD) from EEG signals, explicitly targeting noisy data. The framework outperforms existing deep learning models, achieving 96.8% accuracy within a 2‑second decision window while using fewer parameters. It represents one of the first approaches to actively mitigate EEG noise in AAD tasks.

RAMamba-Net: A Reliability-Aware and Mamba-Based Multimodal Fusion Network for Auditory Attention Detection

RAMamba-Net is a new multimodal fusion network designed for auditory attention decoding (AAD) that combines EEG and electrooculography (EOG) signals. It uses a Mamba-enhanced band-aware convolutional Transformer to capture EEG band-specific patterns and long-range temporal dynamics, while a dual-branch encoder models EOG temporal and inter-channel dependencies. Cross‑modal attention and a reliability‑aware module estimate sample‑wise modality weights, improving fusion robustness and achieving a 5.76% accuracy gain over unimodal baselines on two AAD benchmarks.

Adaptive Anisotropic Attention for Axis-Structured Signals

The paper introduces Adaptive Anisotropic Attention (AAA), a method that splits self‑attention into temporal and spatial paths for axis‑structured signals like EEG. A learned gate combines the two paths for each token, and the resulting AXON model outperforms dense attention baselines on six EEG tasks and shows transfer to audio spectrograms. The study demonstrates that aligning attention with the natural axes of structured data provides a beneficial inductive bias.
