This study presents a novel approach combining graph-based data representation with DARTS-optimised MobileViT models, with the objective of enhancing diagnostic accuracy and reliability. The images of the pancreatic CT were transformed into graph structures using the Harris Corner Detection algorithm, which enables the capture of complex spatial relationships. Subsequently, the graph representations were processed using MobileViT models that had been optimised with Differentiable Architecture Search (DARTS), thereby enabling dynamic architectural adaptation. To further enhance classification accuracy, advanced machine learning algorithms, including K-Nearest Neighbours (KNN), Support Vector Machines (SVM), Random Forest (RF), and XGBoost, were applied. The MobileViTv2_ 150 and MobileViTv2_200 models demonstrated remarkable performance, with an accuracy of 97. 33% and an F1 score of 96 . 25%, surpassing the capabilities of traditional CNN and Vision Transformer models. This innovative integration of graph-based deep learning and machine learning techniques demonstrates the potential of the proposed method to establish a new standard for early pancreatic cancer diagnosis. Furthermore, the study highlights the scalability of this approach for broader applications in medical imaging, which could lead to improved patient outcomes.  \nHighlights  \n• The performance of MobileViT models for pancreatic cancer diagnosis was enhanced using DARTS for dynamic optimization.  \n• By converting pancreatic CT images into graph representations, complex structural features can be captured, thereby enhancing diagnostic accuracy.  \n• MobileViT models have been integrated by combining the strengths of CNN architectures and visual transformer (ViT) models in medical imaging.  \n• Classification algorithms have been utilized to improve the classification performance of optimized MobileViT models, achieving superior accuracy and reliability.  \n• Comparative analyses with traditional CNNs and Vision Transformer models highlight the advantages ofthe proposed approach.  \n• This approach has the potential to improve patient outcomes and survival rates by enhancing early pancreatic cancer diagnosis.  \n*Correspondence: Yusuf Alaca [yusufalaca@hitit.edu.tr](yusufalaca@hitit.edu.tr)  \n© The Author(s) 2025.
