Source code Fuzzy Logic: Menentukan nilai akhir semester siswa

Thursday, June 10th, 2021

Berikut adalah code yang saya gunakan sesuai dengan video di youtube. Silahkan kalian modifikasi sesuai dengan kebutuhan, atau barangkali ingin bereksperimen dengan mengubah rule.

import numpy as np
import skfuzzy as fuzz
from skfuzzy import control as ctrl

class fuzzyNilai:
    
    def __init__(self):
    
        self.forum = ctrl.Antecedent(np.arange(0, 11, 1), 'forum')
        self.disiplin = ctrl.Antecedent(np.arange(0, 11, 1), 'disiplin')
        self.NilaiQuizUjian = ctrl.Antecedent(np.arange(0, 11, 1), 'nilai')
        self.NilaiAkhir = ctrl.Consequent(np.arange(0, 101, 1), 'nilaiakhir')
        
    def membership(self):
        self.forum.automf(3)
        self.disiplin.automf(3)
        self.NilaiQuizUjian.automf(3)
        
    def customMembership(self):
        self.membership()
        self.NilaiAkhir['kecil'] = fuzz.trimf(self.NilaiAkhir.universe,[0,0,80])
        self.NilaiAkhir['sedang'] = fuzz.trimf(self.NilaiAkhir.universe,[60,80,100])
        self.NilaiAkhir['tinggi'] = fuzz.trimf(self.NilaiAkhir.universe,[80,100,100])
        
    def rule(self):
        self.membership()
        self.customMembership()
        self.rule1 = ctrl.Rule(self.forum['poor'] | self.disiplin['poor'] | self.NilaiQuizUjian['poor'], self.NilaiAkhir['kecil'])
        
        self.rule2 = ctrl.Rule(self.forum['good'] | self.NilaiQuizUjian['good'], self.NilaiAkhir['tinggi'])
        
        self.rule3 = ctrl.Rule(self.forum['average'] | self.disiplin['average'], self.NilaiAkhir['sedang'])
        
        self.rule4 = ctrl.Rule(self.disiplin['good'], self.NilaiAkhir['tinggi'])
        
        
        
    def controlSystem(self):
        self.rule()
        nilai_ctrl = ctrl.ControlSystem([self.rule1, self.rule2, self.rule3, self.rule4])
        self.scoring = ctrl.ControlSystemSimulation(nilai_ctrl)
        
        self.scoring.input['forum'] = 4
        self.scoring.input['disiplin'] = 4
        self.scoring.input['nilai'] = 1
        
        self.scoring.compute()
        
    def result(self):
        self.controlSystem()
        print(self.scoring.output['nilaiakhir'])
        self.NilaiAkhir.view(sim=self.scoring)

Cara menjalankannya akan saya posting di artikel berikutnya.
