EVA-Net: Interpretable Anomaly Detection for Brain Health via Learning Continuous Aging Prototypes from One-Class EEG Cohorts

arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • EVA-Net has been introduced as a novel framework for interpretable anomaly detection in brain health, leveraging electroencephalography (EEG) data to learn continuous aging prototypes from healthy cohorts. This approach addresses the challenge of establishing a 'normal' baseline in medical data, which is crucial for identifying diseases such as Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD).
  • The development of EVA-Net is significant as it enhances the interpretability of EEG models, which have traditionally been viewed as black boxes. By employing a sparsified-attention Transformer and Variational Information Bottleneck, EVA-Net aims to provide a robust representation of EEG data, potentially improving diagnostic accuracy and patient outcomes in neurodegenerative conditions.
  • This advancement reflects a broader trend in artificial intelligence and medical research, where the integration of deep learning techniques is increasingly applied to EEG and neuroimaging data. The focus on interpretability and robustness in models like EVA-Net aligns with ongoing efforts to develop reliable biomarkers for cognitive aging and neurodegenerative diseases, highlighting the importance of addressing data imperfections in medical diagnostics.
