A Brain-Inspired Computational Framework for Image-Based Skin Cancer Risk Assessment
Skin cancer risk prediction is critical for early diagnosis, but existing methods struggle with feature representation and computational efficiency. This study introduces Bicom, a novel brain-inspired framework that integrates efficient attention mechanisms, multi-scale feature fusion, and confidence-aware refinement via a Spiking Neural Network (SNN). Bicom employs F-ResNeSt for multi-scale feature extraction with linear-complexity Linformer attention, and L-CoAtNet for scalable classification. Extensive experiments on public and subject datasets demonstrate Bicom's superior accuracy, robustness, and scalability.

Bicom integrates F-ResNeSt for efficient multi-scale feature extraction, L-CoAtNet for scalable classification, and a brain-inspired Spiking Neural Network (SNN) module for confidence-aware refinement. F-ResNeSt enhances ResNeSt with Feature Pyramid Network (FPN) and Linformer-based linear-complexity attention for global dependency modeling. L-CoAtNet replaces CoAtNet's relative attention with Linformer-based attention to reduce computational complexity. The SNN module selectively refines predictions for ambiguous samples, enhancing robustness.
Comprehensive experiments on public (ISIC) and subject datasets demonstrate Bicom's competitive performance across multiple evaluation metrics. It consistently achieves superior accuracy (94.57%), precision (93.67%), recall (95.32%), specificity (96.81%), and AUC (97.66%). Ablation studies confirm that Linformer-based attention, FPN, and the SNN module contribute complementary benefits, enhancing predictive robustness and generalization capabilities.
Current limitations include reliance on publicly available datasets, which may not fully capture real-world clinical diversity, and increased model complexity/computational cost due to integrating multiple architectures. Future work will focus on validating with large-scale multi-center clinical datasets, exploring lightweight model compression/optimization strategies, extending to multi-disease/multimodal applications, and advancing brain-inspired computing mechanisms for enhanced uncertainty modeling and decision reliability.

Real-world Clinical Impact: Enhanced Diagnostic Confidence
In a busy dermatology clinic, the Bicom framework was deployed to assist physicians in skin lesion assessment. For challenging cases where the initial L-CoAtNet classification showed low confidence (e.g., probability near 0.5), the brain-inspired Spiking Neural Network (SNN) module was automatically activated. This SNN provided a 'second opinion' by processing the image with adaptive neural responses, mimicking a human expert's deeper examination. This dynamic refinement mechanism significantly reduced misclassification rates for ambiguous samples, improving overall diagnostic accuracy and, critically, boosting physician trust in the AI's recommendations. Instead of a 'black box' output, Bicom offered a more reliable, context-aware decision support, especially for subtle or atypical lesions that often challenge even experienced clinicians.
Key Outcome: Improved physician trust and reduced diagnostic errors in ambiguous cases.
