Topological Data Analysis Meets Formal Concept Analysis: A Unified Lattice-Theoretic Framework

While TDA and FCA (see Ganter et al., 1998) have both been applied separately to data mining, no one has systematically integrated them. The idea is to treat persistence modules (which track how features persist over filtrations) as lattices, naturally aligning with FCA’s concept lattice structure. This would allow one to organize topological features into a hierarchy of concepts, potentially revealing new multiscale patterns in the data. Such a synthesis could yield interpretable, multi-resolution data summaries—combining the strengths of TDA’s shape analysis with FCA’s rigor in formalizing attribute relationships. This direction is especially promising for exploratory data analysis, knowledge discovery, and explainable AI, providing a new mathematical language for summarizing complex data.
