An improved ICEEMDAN-depth hybrid network model integrating multimodal data for the screening of diabetic peripheral neuropathy
This study proposes a novel deep learning framework for the non-invasive screening of Diabetic Peripheral Neuropathy (DPN) by fusing Photoplethysmography (PPG) and Electrocardiogram (ECG) signals. It introduces an adaptive denoising method combining PSO-optimized ICEEMDAN with wavelet thresholding to enhance signal quality. A novel Spatial-Gramian Angular Field-Recurrence Plot (SGR) encoding transforms 1D time-series signals into RGB images, capturing dynamic correlation features. Finally, an enhanced lightweight network (Afsharid), featuring multi-branch depth-wise convolution and a spatial hybrid self-attention mechanism, processes these images for high-precision DPN classification. The model achieves 93.89% accuracy, 93.21% sensitivity, and 94.52% precision on a multi-cycle dataset, significantly outperforming baseline models like EfficientNetV2 by 6.52% in accuracy, demonstrating its potential for early DPN detection and monitoring.

Afsharid Network: Beyond EfficientNetV2
The Afsharid network, an enhanced lightweight model, integrates multi-branch depth-wise convolution and a spatial hybrid self-attention mechanism. This design significantly improves upon baseline models like EfficientNetV2, achieving a 6.52% higher accuracy in DPN classification. Its ability to capture complex spatial graph features efficiently, coupled with robust cross-modal fusion, makes it highly suitable for real-time clinical applications and portable point-of-care devices. This architecture balances computational efficiency with superior discriminative power, crucial for effective DPN screening.
Towards Accessible DPN Screening
This framework offers a non-invasive, high-precision solution for early DPN detection, addressing the limitations of conventional methods (invasiveness, complexity, cost). By leveraging readily available PPG and ECG signals, it facilitates convenient acquisition and daily monitoring. Its robust performance and potential for integration into portable devices make it an ideal auxiliary tool for primary care settings, empowering non-specialist nurses and general practitioners to identify high-risk individuals for timely specialist referral, ultimately improving resource allocation and patient outcomes in DPN management.
