Tensor modeling and factorization schemes for identifying HFpEF subtypes using phenotypic variables and genetic variants as modes. The data tensor 𝒳 models the interactions among modes including patient, phenotypic variables, and genetic variants. The factor matrix ℬ in Tucker factorization or the length-P factor vectors βi’s in CP factorization correspond to groups of phenotypic variables that characterize HFpEF subtypes. The factor matrix 𝒞 in Tucker factorization or the length-V factor vectors γi’s in CP factorization correspond to groups of genetic variants that characterize HFpEF subtypes. LV = left ventricle.
