Researchers have developed a new patch-based topological data analysis (TDA) method for computed tomography (CT) imaging, aiming to improve the performance of machine learning models used in medical diagnosis. This novel approach addresses the limitations of existing methods, such as the cubical complex algorithm, which struggle with high-resolution images and computational costs. The patch-based TDA demonstrated superior classification performance and reduced processing time, showing significant improvements in accuracy, AUC, sensitivity, specificity, and F1 score across various datasets. To support its adoption, the team has released a Python package named Patch-TDA. AI
