S. no | Bipolar fuzzy faces | Positive membership \({\mu }_{\mathring{\rm A}}^{\wp }(\mathcalligra{x})\) | Negative membership \({\mu }_{\mathcal{B}}^{\mathbb{N}}(\mathcalligra{y})\) |
|---|---|---|---|
1 | \({\mathfrak{f}}_{1}\) | 0.4 |  − 0.6 |
2 | \({\mathfrak{f}}_{2}\) | 0.375 |  − 0.875 |
3 | \({\mathfrak{f}}_{3}\) | 0.6 |  − 0.875 |
4 | \({\mathfrak{f}}_{4}\) | 0.375 |  − 0.875 |
