Clinical Report: VesselMetaKAN Framework for Diabetic Retinopathy Classification

Overview

VesselMetaKAN is a two-stage framework designed for the interpretable classification of diabetic retinopathy (DR) using vessel guidance and meta-learning. It achieved significant performance metrics on the APTOS 2019 dataset.

Background

Diabetic retinopathy is a major cause of preventable blindness, affecting millions globally. Early detection through automated grading systems is essential for effective public health interventions. However, existing deep learning methods face challenges in accurately identifying vascular structures critical for DR diagnosis.

Data Highlights

Key Findings

• VesselMetaKAN integrates vessel guidance with meta-learning for DR classification.
• Stage 1 utilizes GMF-SwinUnet for vessel segmentation with advanced techniques like Frangi-guided attention fusion.
• Stage 2 employs KAN-MAML for interpretable decision-making and meta-learning.
• Ablation studies confirmed the importance of vessel guidance and KAN-based interpretability.
• VesselMetaKAN outperformed EfficientNet-B4 in key grading metrics with statistical significance (p < 0.05).

Clinical Implications

The VesselMetaKAN framework offers a robust and interpretable solution for diabetic retinopathy grading, addressing critical challenges in vessel segmentation and feature learning.

Conclusion

VesselMetaKAN represents a significant advancement in automated diabetic retinopathy classification, combining interpretability with high performance.
