Sheaf Theory and Machine Learning

  • Introduction to Sheaf Theory

    • Overview: Introduce sheaf theory as a branch of mathematics concerned with the consistent assignment of algebraic structures across overlapping local patches of a topological space.
    • Historical Context: Briefly discuss the origins of sheaf theory in algebraic topology and its applications across various fields of mathematics.
  • Sheaves in Data Representation and Analysis

    • Data as Topological Spaces: Explore how complex datasets can be viewed as topological spaces, where sheaf theory applies.
    • Local-to-Global Inference: Discuss how sheaf theory facilitates the integration of local data patterns to infer global structures, enhancing tasks like data fusion, noise reduction, and anomaly detection.
  • Applications of Sheaf Theory in Machine Learning

    • Sheaves for Multi-Resolution Analysis: Examine case studies where sheaf theory has been used to analyze data at multiple resolutions or scales.
    • Topological Data Analysis (TDA) and Sheaves: Discuss the synergy between TDA and sheaf theory in uncovering hidden structures in high-dimensional data.
