    The study developed a lightweight attention-enhanced MobileNetV3 model for classifying gastrointestinal precancerous lesions.

  • 2

    The model achieved an overall accuracy of 99.10% and 100% precision for polyp detection, significantly improving diagnostic performance.

  • 3

    Ablation experiments confirmed the effectiveness of the Spatial-Channel Attention module, enhancing core metrics without increasing computational load.

  • 4

    The model's lightweight design allows real-time deployment on endoscopic devices, addressing barriers to clinical adoption of AI.

  • 5

    GradCAM visualizations demonstrated the model's focus on clinically relevant areas, aligning AI reasoning with endoscopists' observation habits.
