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.
