Abstract:
\begin{document} Topological Data Analysis (TDA) is a modern approach for analysing complex datasets using tools from algebraic topology, the branch of mathematics concerned with studying the shape of spaces. Unlike conventional statistics, which often assumes linear or low-dimensional structures, TDA is designed to uncover hidden patterns and global organisation in high-dimensional and noisy data. There are two main approaches to TDA: Persistent Homology (PH) and Mapper. In this talk, we will focus on Mapper, which creates a simplified graph-based representation of high-dimensional data. It works by partitioning the dataset, analysing local structures, and connecting them into a network called a Mapper graph. We end by discussing an application for breast cancer analysis. \end{document}
