This study presents TRIAD-Influenza (TRIAD: Token-Residue-Integrated Architecture for Drift), a multi-view transformer that combines (i) codon- and residue-level sequence representations, (ii) structure-derived residue interaction features from predicted HA/NA models, and (iii) an embedding-space phylogeny that captures cluster and drift context. The gene discussed is XK; the disease is influenza.
