MULTIPLE DISEASE PREDICTION ABSTRACT In a world where advanced medical devices coexist with significant time constraints in healthcare, we are launching a machine learning project to identify patients with serious diseases (heart disease, diabetes, pneumonia and brain tumor) at an early stage to facilitate timeliness and efficiency. treatment . Through careful data collection, analysis and cleaning of various datasets, we determined the most suitable algorithms and achieved significant accuracy. Relying on cutting-edge technologies ensures robust and accurate predictions for all four models, while the user-friendly Flask website simplifies the process, making early disease detection easier and potentially life-saving for patients and healthcare professionals. This project combines machine learning, data analytics and data science to bridge the gap between the latest diagnostic tools and time-sensitive healthcare services. INTRODUCTION In our information world, where i...
