A machine learning based approach to predicting pancreatic diseases

This study addresses the critical challenge of early diagnosis of pancreatic disorders, including pancreatitis and pancreatic cancer, by constructing an ensemble machine learning model aimed at improving diagnostic accuracy. Recognizing the limitations of current diagnostic methods, we focused on leveraging advanced machine learning techniques. The study involved the creation and preprocessing of the Urinary Biomarkers for Pancreatic Cancer dataset, employing a range of feature selection methods such as ANOVA, Chi-Squared, Genetic Algorithms, Artificial Bee Colony, and Particle Swarm Optimization. Our Super Learner model, which integrated the strengths of base models (Decision Tree, Random Forest, and Support Vector Machine) with Logistic Regression as the meta-learner, achieved exceptional performance, demonstrating an accuracy of 99.1%. The superior performance of the Super Learner model underscores the necessity of ensemble approaches for enhancing model accuracy and generalizability. The integration of feature selection methods, especially PSO, further improved input data quality, boosting the Super Learner model's efficacy. Based on these findings, we recommend prioritizing advanced feature selection techniques, particularly PSO, and leveraging ensemble learning methods to enhance predictive models. Future research should include more diverse biomarkers and larger datasets, and collaboration between machine learning experts and medical professionals is essential to ensure clinical relevance. Ongoing validation in real-world settings is crucial for refining these models and confirming their effectiveness in early diagnosis, ultimately improving patient outcomes.
