Table 8 The PC logic and the fuzzy logic for the regulatory effects of genes G₁ and G₂ on the target, utilizing continuous gene expression data. exp_A and exp_B denote the expression levels of genes G₁ and G₂, respectively

\( NOT\left({\mathrm{G}}_1\right)=\overline{{\mathrm{G}}_1} \)

\( 1-{\mathit{\exp}}_{{\mathrm{G}}_1} \)

\( 1-{\mathit{\exp}}_{{\mathrm{G}}_1} \)

AND(G₁, G₂) = G₁ ⋀ G₂

\( {\mathit{\exp}}_{{\mathrm{G}}_1}\ast {\mathit{\exp}}_{{\mathrm{G}}_2} \)

\( \mathit{\min}\left({\mathit{\exp}}_{{\mathrm{G}}_1},{\mathit{\exp}}_{{\mathrm{G}}_2}\right) \)

OR(G₁, G₂) = G₁ ⋁ G₂

\( {\mathit{\exp}}_{G_1}+{\mathit{\exp}}_{G_2}-{\mathit{\exp}}_{G_1}\ast {\mathit{\exp}}_{{\mathrm{G}}_2} \)

\( \mathit{\min}\left(1,{\mathit{\exp}}_{{\mathrm{G}}_1}+{\mathit{\exp}}_{{\mathrm{G}}_2}\right) \)
