This matching corresponds to a permutationπ∈S n such that (D ˆZϕ−1)j,π(j) ̸= 0,∀j∈ {1,2,

SinceD ˆZϕ−1 is invertible, its rows are linearly independent, so for every subsetS⊆R, the corresponding rows have a nonzero determinant, implying that |{k∈C| ∃j∈S, D ˆZϕ−1 j,k ̸= 0}| ≥ |S| · 2026

Diverse dictionary learning identifies intersections, complements, and dependency structures of latent variables from data X = g(Z) up to indeterminacies, and full identifiability when structural diversity is sufficient.
