Szemerédi’s Regularity Lemma (SRL) is a crucial tool in the analysis of huge graphs, having made significant contributions in the proof of some sensational results in mathematics. Traditional protein classification methods primarily rely on sequence, structure, or function similarity, resulting in classifications by protein family or superfamily, disregarding the significance of the Protein-Protein Interaction (PPI) network. In this talk, we will introduce some interesting findings in PPI network which was partitioned by SRL .
