Deep Learning has contributed significantly to the advances made in fields of Medical Imaging and Computer Aided Diagnosis (CAD). Although a variety (DL) models exist for purposes image classification medical domain, more analysis needs be conducted on their decision-making processes. For this reason, several novel Explainable AI (XAI) techniques have been proposed recent years better understand DL models. Currently, professionals rely visual inspections diagnose potential diseases endoscopic imaging preliminary stages. However, we believe that use automated systems can enhance both efficiency such diagnoses. The aim study is increase reliability model predictions within field by implementing transfer learning balanced subset Kvasir-capsule, Wireless Capsule Endoscopy dataset. This includes top 9 classes dataset training testing. results obtained were an F1-score 97%±1% Vision Transformer model, although other as MobileNetv3Large ResNet152v2 also able achieve F1-scores over 90%. These are currently highest-reported metrics data, improving upon prior studies done same heatmaps XAI techniques, including GradCAM, GradCAM++, LayersCAM, LIME, SHAP presented form evaluated according highlighted regions importance. effort decisions top-performing look beyond black-box nature.

Circular and haustral folds in the lower gastrointestinal tract (small large intestines) are major obstructions impeding locomotion of capsule robots for endoscopic diagnosis. Understanding interactions between these is critical design control to reach areas clinical interest. This paper proposes a new mathematical model capsule-intestine interaction based on our previous work (Yan et al. 2022) by introducing capsule's rotation during fold crossing. The resisting force predicted more consistent with finite element experimental results compared model. It found that obstructive effect stronger higher thinner stiffer intestine. For robot, which actuated periodically driven inner mass, excitation required overcome larger force. Moreover, bifurcation analysis reveals small always incurs simple period-1 motion while may result various complex dynamics before findings this help robotics engineers evaluate their designs terms propulsion understand tract.
